Add a couple of tests to check that we don't leak inodes or dquots if CoW recovery fails and therefore the mount fails. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

|
# Ensure that we don't leak quota inodes when CoW recovery fails.
|
|
#
|
|
# Use xfs_fsr to inject bmap redo items in the log for a linked file and
|
|
# an unlinked file; enable quota so that we always mount with the quota
|
|
# inodes; and then corrupt the refcount btree to ensure that the CoW
|
|
# garbage collection (and therefore the mount) fail.
|
|
#
|
|
# On a subsequent mount attempt, we should be able to replay the bmap
|
|
# items for the linked and unlinked files without prematurely truncating
|
|
# the unlinked inode and without leaking the linked inode, and we should
|
|
# be able to release the quota inodes when we're aborting the mount. We
|
|
# also should not leak dquots.
