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