The problem is that NFSv4 is trying to do an allocation from
fl_release_private (in order to send a RELEASE_LOCKOWNER call). That
function can be called while holding the inode->i_lock, and it's
currently set up to do __GFP_WAIT allocations. v4.1 code has a
similar problem.
This patch adds a work_struct to the nfs4_lock_state and has the code
queue the free_lock_state operation to nfsiod.

Do the following set of ops with a file on a NFSv4 mount:
exec 3>>/file/on/nfsv4
flock -x 3
exec 3>&-
You'll see the LOCK request go across the wire, but no LOCKU when the
file is closed.
What happens is that the fd is passed across a fork, and the final close
is done in a different process than the opener. That makes
__nfs4_find_lock_state miss finding the correct lock state because it
uses the fl_pid as a search key. A new one is created, and the locking
code treats it as a delegation stateid (because NFS_LOCK_INITIALIZED
isn't set).
The root cause of this breakage seems to be commit 77041ed9b49a9e
(NFSv4: Ensure the lockowners are labelled using the fl_owner and/or
fl_pid).
That changed it so that flock lockowners are allocated based on the
fl_pid. I think this is incorrect. flock locks should be "owned" by the
struct file, and that is already accounted for in the fl_owner field of
the lock request when it comes through nfs_flock.
This patch basically reverts the above commit and with it, a LOCKU is
sent in the above reproducer.

We need to hold cinfo lock while setting bucket->wlseg and adding req to nwritten
list at the same time. Otherwise there might be a window where nwritten list
is empty yet we set bucket->wlseg, in which case ff_layout_scan_ds_commit_list()
may end up clearing bucket->wlseg incorrectly, casuing client to oops later on.
This was found when testing flexfile layout but filelayout has the same problem.

POSIX states that open("foo", O_CREAT|O_RDONLY, 000) should succeed if
the file "foo" does not already exist. With the current NFS client,
it will fail with an EACCES error because of the permissions checks in
nfs4_opendata_access().
Fix is to turn that test off if the server says that we created the file.

The refcounting on nfs_pgio_header was related to there being (possibly)
more than one nfs_pgio_data. Now that nfs_pgio_data has been merged into
nfs_pgio_header, there is no reason to do this ref counting. Just call
the completion callback on nfs_pgio_release/nfs_pgio_error.

struct nfs_pgio_data only exists as a member of nfs_pgio_header, but is
passed around everywhere, because there used to be multiple _data structs
per _header. Many of these functions then use the _data to find a pointer
to the _header. This patch cleans this up by merging the nfs_pgio_data
structure into nfs_pgio_header and passing nfs_pgio_header around instead.

nfs_rw_header was used to allocate an nfs_pgio_header along with an
nfs_pgio_data, because a _header would need at least one _data.
Now there is only ever one nfs_pgio_data for each nfs_pgio_header -- move
it to nfs_pgio_header and get rid of nfs_rw_header.

Pull xfs update from Dave Chinner:
"This update contains:
- conversion of the XFS core to pass negative error numbers
- restructing of core XFS code that is shared with userspace to
fs/xfs/libxfs
- introduction of sysfs interface for XFS
- bulkstat refactoring
- demand driven speculative preallocation removal
- XFS now always requires 64 bit sectors to be configured
- metadata verifier changes to ensure CRCs are calculated during log
recovery
- various minor code cleanups
- miscellaneous bug fixes
The diffstat is kind of noisy because of the restructuring of the code
to make kernel/userspace code sharing simpler, along with the XFS wide
change to use the standard negative error return convention (at last!)"

We need to treat both inodes identically from a page cache point of
view when prepareing them for extent swapping. We don't do this
right now - we assume that one of the inodes empty, because that's
what xfs_fsr currently does. Remove this assumption from the code.
While factoring out the flushing and related checks, move the
transactions reservation to immeidately after the flushes so that we
don't need to pick up and then drop the ilock to do the transaction
reservation. There are no issues with aborting the transaction it if
the checks fail before we join the inodes to the transaction and
dirty them, so this is a safe change to make.

xfs_swap_extents() holds the ilock over a call to
filemap_write_and_wait(), which can then try to write data and take
the ilock. That causes a self-deadlock.
Fix the deadlock and clean up the code by separating the locking
appropriately. Add a lockflags variable to track what locks we are
holding as we gain and drop them and cleanup the error handling to
always use "out_unlock" with the lockflags variable.

Move the IO flag definitions to xfs_inode.h and kill the header file
as it is now empty.
Removing the xfs_vnode.h file showed up an implicit header include
path:
xfs_linux.h -> xfs_vnode.h -> xfs_fs.h
And so every xfs header file has been inplicitly been including
xfs_fs.h where it is needed or not. Hence the removal of xfs_vnode.h
causes all sorts of build issues because BBTOB() and friends are no
longer automatically included in the build. This also gets fixed.

dquot recovery should add verifiers to the dquot buffers that it
recovers changes into. Unfortunately, it doesn't attached the
verifiers to the buffers in a consistent manner. For example,
xlog_recover_dquot_pass2() reads dquot buffers without a verifier
and then writes it without ever having attached a verifier to the
buffer.
Further, dquot buffer recovery may write a dquot buffer that has not
been modified, or indeed, shoul dbe written because quotas are not
enabled and hence changes to the buffer were not replayed. In this
case, we again write buffers without verifiers attached because that
doesn't happen until after the buffer changes have been replayed.

This was caused by dquot buffer readahead not attaching a verifier
structure to the buffer when readahead was issued, resulting in the
followup read of the buffer finding a valid buffer and so not
attaching new verifiers to the buffer as part of the read.
Also, when a verifier failure occurs, we then read the buffer
without verifiers. Attach the verifiers manually after this read so
that if the buffer is then written it will be verified that the
corruption has been repaired.
Further, when flushing a dquot we don't ask for a verifier when
reading in the dquot buffer the dquot belongs to. Most of the time
this isn't an issue because the buffer is still cached, but when it
is not cached it will result in writing the dquot buffer without
having the verfier attached.

Crash testing of CRC enabled filesystems has resulted in a number of
reports of bad CRCs being detected after the filesystem was mounted.
Errors such as the following were being seen:
XFS (sdb3): Mounting V5 Filesystem
XFS (sdb3): Starting recovery (logdev: internal)
XFS (sdb3): Metadata CRC error detected at xfs_agf_read_verify+0x5a/0x100 [xfs], block 0x1
XFS (sdb3): Unmount and run xfs_repair

XFS (sdb3): metadata I/O error: block 0x1 ("xfs_trans_read_buf_map") error 74 numblks 1
The errors were typically being seen in AGF, AGI and their related
btree block buffers some time after log recovery had run. Often it
wasn't until later subsequent mounts that the problem was
discovered. The common symptom was a buffer with the correct
contents, but a CRC and an LSN that matched an older version of the
contents.
Some debug added to _xfs_buf_ioapply() indicated that buffers were
being written without verifiers attached to them from log recovery,
and Jan Kara isolated the cause to log recovery readahead an dit's
interactions with buffers that had a more recent LSN on disk than
the transaction being recovered. In this case, the buffer did not
get a verifier attached, and os when the second phase of log
recovery ran and recovered EFIs and unlinked inodes, the buffers
were modified and written without the verifier running. Hence they
had up to date contents, but stale LSNs and CRCs.
Fix it by attaching verifiers to buffers we skip due to future LSN
values so they don't escape into the buffer cache without the
correct verifier attached.
This patch is based on analysis and a patch from Jan Kara.

We recently had a bug where buffers were slipping through log
recovery without any verifier attached to them. This was resulting
in on-disk CRC mismatches for valid data. Add some warning code to
catch this occurrence so that we catch such bugs during development
rather than not being aware they exist.
Note that we cannot do this verification unconditionally as non-CRC
filesystems don't always attach verifiers to the buffers being
written. e.g. during log recovery we cannot identify all the
different types of buffers correctly on non-CRC filesystems, so we
can't attach the correct verifiers in all cases and so we don't
attach any. Hence we don't want on non-CRC filesystems to avoid
spamming the logs with false indications.

The commit
83e782e xfs: Remove incore use of XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD
added a new function xfs_sb_quota_from_disk() which swaps
on-disk XFS_OQUOTA_* flags for in-core XFS_GQUOTA_* and XFS_PQUOTA_*
flags after the superblock is read.
However, if log recovery is required, the superblock is read again,
and the modified in-core flags are re-read from disk, so we have
XFS_OQUOTA_* flags in memory again. This causes the
XFS_QM_NEED_QUOTACHECK() test to be true, because the XFS_OQUOTA_CHKD
is still set, and not XFS_GQUOTA_CHKD or XFS_PQUOTA_CHKD.
Change xfs_sb_from_disk to call xfs_sb_quota_from disk and always
convert the disk flags to in-memory flags.
Add a lower-level function which can be called with "false" to
not convert the flags, so that the sb verifier can verify
exactly what was on disk, per Brian Foster's suggestion.

The offset and length parameters are converted from bytes to basic
blocks by xfs_vn_fiemap(). The BTOBB() converter rounds the value up to
the nearest basic block. This leads to unexpected behavior when
unaligned offsets are provided to FIEMAP.
Fix the conversions of byte values to block values to cover the provided
offsets. Round down the start offset to the nearest basic block.
Calculate the end offset based on the provided values, round up and
calculate length based on the start block offset.

To fetch the file system number tables, we currently just ignore the
errors and proceed to loop over the next AG or bump agino to the next
chunk in case of btree operations failed, that is not properly because
those errors might hint us potential file system problems.
This patch rework xfs_inumbers() to handle the btree operation errors
as well as the loop conditions.

xfs_bukstat_one doesn't have any failure case that would go away when
called through xfs_bulkstat, so remove the fallback and the now unessecary
xfs_bulkstat_single function.

Trying to support tiny disks only and saving a bit memory might have
made sense on an SGI O2 15 years ago, but is pretty pointless today.
Remove the rarely tested codepath that uses various smaller in-memory
types to reduce our test matrix and make the codebase a little bit
smaller and less complicated.

We are intended to check up uflags against FS_PROJ_QUOTA rather than
FS_USER_UQUOTA once more, it looks to me like a typo, but might cause
the project quota metadata space can not be removed.

xfs_set_inode32() caught my eye because it had weird spacing around
the "-1's". In cleaning that up, I realized that the assignment in
the declaration of "ino" is never used; it's rewritten before it
gets read.
Drop the ino initializer from its declaration since it's not used,
and move the agino initialization into the body of the function,
mostly so that we can have pretty whitespace and not exceed 80
columns. :)
