As Al Viro correctly pointed out, there is no need to return
the whole structure to check the error.

When counting and checking hard links in an ntfs file record,
struct MFT_REC {
struct NTFS_RECORD_HEADER rhdr; // 'FILE'
__le16 seq; // 0x10: Sequence number for this record.
>> __le16 hard_links; // 0x12: The number of hard links to record.
__le16 attr_off; // 0x14: Offset to attributes.
...
the ntfs3 driver ignored short names (DOS names), causing the link count
to be reduced by 1 and messages to be output to dmesg.
For Windows, such a situation is a minor error, meaning chkdsk does not report
errors on such a volume, and in the case of using the /f switch, it silently
corrects them, reporting that no errors were found. This does not affect
the consistency of the file system.
Nevertheless, the behavior in the ntfs3 driver is incorrect and
changes the content of the file system. This patch should fix that.
PS: most likely, there has been a confusion of concepts
MFT_REC::hard_links and inode::__i_nlink.

atomic_open is an optional VFS operation, and is primarily for network
filesystems. NFS (for instance) can just send an open call for the last
path component rather than doing a lookup and then having to follow that
up with an open when it doesn't have a dentry in cache.
ntfs3 is a local filesystem however, and its atomic_open just does a
typical lookup + open, but in a convoluted way. atomic_open will also
make directory leases more difficult to implement on the filesystem.
Remove ntfs_atomic_open.

We are trying to get rid of all multiplications from allocation
functions to prevent integer overflows[1]. Here the multiplication is
obviously safe, but using kcalloc() is more appropriate and improves
readability. This patch has no effect on runtime behavior.

The parameter passed to kfree was 5a5a5a5a, which corresponds to the target field of
the jffs_inode_info structure. It was found that all variables in the jffs_inode_info
structure were 5a5a5a5a, except for the first member sem. It is suspected that these
variables are not initialized because they were set to 5a5a5a5a during memory testing,
which is meant to detect uninitialized memory.The sem variable is initialized in the
function jffs2_i_init_once, while other members are initialized in
the function jffs2_init_inode_info.
The function jffs2_init_inode_info is called after iget_locked,
but in the iget_locked function, the destroy_inode process is triggered,
which releases the inode and consequently, the target member of the inode
is not initialized.In concurrent high pressure scenarios, iget_locked
may enter the destroy_inode branch as described in the code.
Since the destroy_inode functionality of jffs2 only releases the target,
the fix method is to set target to NULL in jffs2_i_init_once.

Pull more btrfs updates from David Sterba:
"A few more updates, mostly stability fixes or user visible changes:
- fix race in zoned mode during device replace that can lead to
use-after-free
- update return codes and lower message levels for quota rescan where
it's causing false alerts
- fix unexpected qgroup id reuse under some conditions
- fix condition when looking up extent refs
- add option norecovery (removed in 6.8), the intended replacements
haven't been used and some aplications still rely on the old one
- build warning fixes"

Although 'norecovery' mount option was marked as deprecated for a long
time and a warning message was printed during the deprecation window,
it's still actively utilized by several projects that need a safer way
to mount a btrfs without any writes.
Furthermore this 'norecovery' mount option is supported by other major
filesystems, which makes it less clear what's our motivation to remove
it.
Re-introduce the 'norecovery' mount option, and output a message to recommend
'rescue=nologreplay' option.

At lookup_extent_data_ref() we are incorrectly checking if we are at the
last slot of the last leaf in the extent tree. We are returning -ENOENT
if btrfs_next_leaf() returns a value greater than 1, but btrfs_next_leaf()
never returns anything greater than 1:
1) It returns < 0 on error;
2) 0 if there is a next leaf (or a new item was added to the end of the
current leaf after releasing the path);
3) 1 if there are no more leaves (and no new items were added to the last
leaf after releasing the path).
So fix this by checking if the return value is greater than zero instead
of being greater than one.

While loading a zone's info during creation of a block group, we can race
with a device replace operation and then trigger a use-after-free on the
device that was just replaced (source device of the replace operation).
This happens because at btrfs_load_zone_info() we extract a device from
the chunk map into a local variable and then use the device while not
under the protection of the device replace rwsem. So if there's a device
replace operation happening when we extract the device and that device
is the source of the replace operation, we will trigger a use-after-free
if before we finish using the device the replace operation finishes and
frees the device.
Fix this by enlarging the critical section under the protection of the
device replace rwsem so that all uses of the device are done inside the
critical section.

If we delete subvolumes whose ID is the largest in the filesystem, then
unmount and mount again, then btrfs_init_root_free_objectid on the
tree_root will select a subvolid smaller than that one and thus allow
reusing it.
If we are also using qgroups (and particularly squotas) it is possible
to delete the subvol without deleting the qgroup. In that case, we will
be able to create a new subvol whose id already has a level 0 qgroup.
This will result in re-using that qgroup which would then lead to
incorrect accounting.

On filesystems without enabled quotas there's still a warning message in
the logs when rescan is called. In that case it's not a problem that
should be reported, rescan can be called unconditionally. Change the
error code to ENOTCONN which is used for 'quotas not enabled' elsewhere.
Remove message (also a warning) when rescan is called during an ongoing
rescan, this brings no useful information and the error code is
sufficient.
Change message levels to debug for now, they can be removed eventually.

Currently, each DEFLATE stream takes one 32 KiB permanent internal
window buffer even if there is no running instance which uses DEFLATE
algorithm.
It's unexpected and wasteful on embedded devices with limited resources
and servers with hundreds of CPU cores if DEFLATE is enabled but unused.

Most of the callers of erofs_read_metabuf() have the following form:
block = erofs_blknr(sb, offset);
off = erofs_blkoff(sb, offset);
p = erofs_read_metabuf(...., erofs_pos(sb, block), ...);
if (IS_ERR(p))
return PTR_ERR(p);
q = p + off;
// no further uses of p, block or off.
The value passed to erofs_read_metabuf() is offset rounded down to block
size, i.e. offset - off. Passing offset as-is would increase the return
value by off in case of success and keep the return value unchanged in
in case of error. In other words, the same could be achieved by
q = erofs_read_metabuf(...., offset, ...);
if (IS_ERR(q))
return PTR_ERR(q);
This commit convert these simple cases.

Al Viro has a series of "->bd_inode elimination" which touches several
subsystems, but he also has EROFS-specific further cleanup patches
which I tend to go with EROFS tree for more testing.
Let's merge "#misc.erofs" as Al suggested in the previous email [1]:
"#misc.erofs (the first two commits) is put into never-rebased mode;
you pull it into your tree and do whatever's convenient with the rest.
I merge the same branch into block_device work; that way it doesn't
cause conflicts whatever else happens in our trees."

the btree key cache uses the srcu struct created/destroyed by
btree_iter.c; btree_iter needs to be exited last.

verify_replicas_entry() is only for newly created replicas entries -
existing entries on disk may have unknown data types, and we have real
verifiers for them.

This fixes an assertion pop in btree_iter.c that checks for forgetting
to pass a snapshot ID when iterating over snapshots btrees.

This fixes missing guards on trying to calculate a checksum with an
invalid/unknown checksum type; moving the guards up to e.g. btree_io.c
might be "more correct", but doesn't buy us anything - an unknown
checksum type will always be flagged as at least a checksum error so we
aren't losing any safety doing it this way and it makes it less likely
to accidentally pop an assert we don't want.

Don't put error pointers in bch_fs, that's gross.
This fixes (?) the check in bch2_checksum_type_valid() - depending on
our error paths, or depending on what our error paths are doing it at
least makes the code saner.

We additionally need to be going inconsistent if passed an invalid
snapshot ID; that patch will need more thorough testing.

We can't disallow unknown data_types in verify() - we have to preserve
them unchanged for backwards compat; that means we have to add a few
more guards.
