# Ensure that we don't leak inodes when CoW recovery fails.
|
|
#
|
|
# Use xfs_fsr to inject bmap redo items in the log for a linked file and
|
|
# an unlinked file; 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 all the inodes when we're aborting the mount.
