* xfs: fix delalloc quota accounting on failureDave Chinner2012-05-211-1/+1
| | | | | | | | | | | | | | | | | | xfstest 270 was causing quota reservations way beyond what was sane (ten to hundreds of TB) for a 4GB filesystem. There's a sign problem in the error handling path of xfs_bmapi_reserve_delalloc() because xfs_trans_unreserve_quota_nblks() simple negates the value passed - which doesn't work for an unsigned variable. This causes reservations of close to 2^32 block instead of removing a reservation of a handful of blocks. Fix the same problem in the other xfs_trans_unreserve_quota_nblks() callers where unsigned integer variables are used, too.

* xfs: don't assert on delalloc regions beyond EOFDave Chinner2012-05-141-2/+14
| | | | | | | | | | | | | | | | | | | When we are doing speculative delayed allocation beyond EOF, conversion of the region allocated beyond EOF is dependent on the largest free space extent available. If the largest free extent is smaller than the delalloc range, then after allocation we leave a delalloc extent that starts beyond EOF. This extent cannot *ever* be converted by flushing data, and so will remain there until either the EOF moves into the extent or it is truncated away. Hence if xfs_getbmap() runs on such an inode and is asked to return extents beyond EOF, it will assert fail on this extent even though there is nothing xfs_getbmap() can do to convert it to a real extent. Hence we should simply report these delalloc extents rather than assert that there should be none. Signed-off-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Ben Myers <bpm@sgi.com>
* xfs: fix deadlock in xfs_rtfree_extentKamal Dasu2012-03-221-0/+9
| | | | | | | | | | | | | | | | | To fix the deadlock caused by repeatedly calling xfs_rtfree_extent - removed xfs_ilock() and xfs_trans_ijoin() from xfs_rtfree_extent(), instead added asserts that the inode is locked and has an inode_item attached to it. - in xfs_bunmapi() when dealing with an inode with the rt flag call xfs_ilock() and xfs_trans_ijoin() so that the reference count is bumped on the inode and attached it to the transaction before calling into xfs_bmap_del_extent, similar to what we do in xfs_bmap_rtalloc.

* xfs: fallback to vmalloc for large buffers in xfs_getbmapDave Chinner2012-03-151-3/+10
| | | | | | | | | | | | | | xfs_getbmap uses for a large buffer for extents, which is kmalloc'd. This can fail after the system has been running for some time as it is a high order allocation. Add a fallback to vmalloc so that it doesn't require contiguous memory and so won't randomly fail on files with large extent lists.

* xfs: remove the i_size field in struct xfs_inodeChristoph Hellwig2012-01-171-9/+6
| | | | | | | | | | | | | | | | | | | | | | | | | There is no fundamental need to keep an in-memory inode size copy in the XFS inode. We already have the on-disk value in the dinode, and the separate in-memory copy that we need for regular files only in the XFS inode. Remove the xfs_inode i_size field and change the XFS_ISIZE macro to use the VFS inode i_size field for regular files. Switch code that was directly accessing the i_size field in the xfs_inode to XFS_ISIZE, or in cases where we are limited to regular files direct access of the VFS inode i_size field. This also allows dropping some fairly complicated code in the write path which dealt with keeping the xfs_inode i_size uptodate with the VFS i_size that is getting updated inside ->write_end. Note that we do not bother resetting the VFS i_size when truncating a file that gets freed to zero as there is no point in doing so because the VFS inode is no longer in use at this point. Just relax the assert in xfs_ifree to only check the on-disk size instead.

| | | | | | | | | | | | | | We spent a lot of effort to maintain this field, but it always equals to the fork size divided by the constant size of an extent. The prime use of it is to assert that the two stay in sync. Just divide the fork size by the extent size in the few places that we actually use it and remove the overhead of maintaining it. Also introduce a few helpers to consolidate the places where we actually care about the value.

* xfs: fix allocation length overflow in xfs_bmapi_write()Dave Chinner2011-12-021-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | When testing the new xfstests --large-fs option that does very large file preallocations, this assert was tripped deep in xfs_alloc_vextent(): XFS: Assertion failed: args->minlen <= args->maxlen, file: fs/xfs/xfs_alloc.c, line: 2239 The allocation was trying to allocate a zero length extent because the lower 32 bits of the allocation length was zero. The remaining length of the allocation to be done was an exact multiple of 2^32 - the first case I saw was at 496TB remaining to be allocated. This turns out to be an overflow when converting the allocation length (a 64 bit quantity) into the extent length to allocate (a 32 bit quantity), and it requires the length to be allocated an exact multiple of 2^32 blocks to trip the assert. Fix it by limiting the extent lenth to allocate to MAXEXTLEN. Signed-off-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Ben Myers <bpm@sgi.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
* xfs: simplify xfs_trans_ijoin* againChristoph Hellwig2011-10-111-2/+2
| | | | | | | | | | | | | | | | | | | There is no reason to keep a reference to the inode even if we unlock it during transaction commit because we never drop a reference between the ijoin and commit. Also use this fact to merge xfs_trans_ijoin_ref back into xfs_trans_ijoin - the third argument decides if an unlock is needed now. I'm actually starting to wonder if allowing inodes to be unlocked at transaction commit really is worth the effort. The only real benefit is that they can be unlocked earlier when commiting a synchronous transactions, but that could be solved by doing the log force manually after the unlock, too.

| | | | | | | | | | | | | | | | | | | | | | | | xfs_bmapi() currently handles both extent map reading and allocation. As a result, the code is littered with "if (wr)" branches to conditionally do allocation operations if required. This makes the code much harder to follow and causes significant indent issues with the code. Given that read mapping is much simpler than allocation, we can split out read mapping from xfs_bmapi() and reuse the logic that we have already factored out do do all the hard work of handling the extent map manipulations. The results in a much simpler function for the common extent read operations, and will allow the allocation code to be simplified in another commit. Once xfs_bmapi_read() is implemented, convert all the callers of xfs_bmapi() that are only reading extents to use the new function.
