Subject: [PATCH 4.14 10/31] xfs: truncate transaction does not modify the inobt
Date: Thu, 8 Nov 2018 13:52:34 -0800 [thread overview]
Message-ID: <20181108215130.568724793@linuxfoundation.org> (raw)
In-Reply-To: <20181108215129.641434673@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit a606ebdb859e78beb757dfefa08001df366e2ef5 ]
The truncate transaction does not ever modify the inode btree, but
includes an associated log reservation. Update
xfs_calc_itruncate_reservation() to remove the reservation
associated with inobt updates.
[Amir: This commit was merged for kernel v4.16 and a twin commit was
merged for xfsprogs v4.16. As a result, a small xfs filesystem
formatted with features -m rmapbt=1,reflink=1 using mkfs.xfs
version >= v4.16 cannot be mounted with kernel < v4.16.
For example, xfstests generic/17{1,2,3} format a small fs and
when trying to mount it, they fail with an assert on this very
demonic line:
XFS (vdc): Log size 3075 blocks too small, minimum size is 3717 blocks
XFS (vdc): AAIEEE! Log failed size checks. Abort!
XFS: Assertion failed: 0, file: src/linux/fs/xfs/xfs_log.c, line: 666
The simple solution for stable kernels is to apply this patch,
because mkfs.xfs v4.16 is already in the wild, so we have to
assume that xfs filesystems with a "too small" log exist.
Regardless, xfsprogs maintainers should also consider reverting
the twin patch to stop creating those filesystems for the sake
of users with unpatched kernels.]
