The option parser in the btrfs utility is going to be updated and will accept arguments in a stricter form, namely that options must come before their non-option argument. Otherwise eg. the -f option in send would be understood as another path and not an option leading to many test failures. The canonical form should be: btrfs command subcommand [-options] [arguments] Signed-off-by: David Sterba <dsterba@suse.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

# FS QA Test No. btrfs/077

|
|
# Regression test for a btrfs incremental send issue.
|
|
# If between two snapshots we rename an existing directory named X to Y and
|
|
# make it a child (direct or not) of a new inode named X, we were delaying
|
|
# the move/rename of the former directory unnecessarily, which would result
|
|
# in attempting to rename the new directory from its orphan name to name X
|
|
# prematurely. This made btrfs receive fail with an error message like the
|
|
# following:
|
|
#
|
|
# rename o261-7-0 -> merlin/RC/OSD failed
|
|
#
|
|
# This issue was a regression in the 3.16 kernel and got fixed by the following
|
|
# linux kernel btrfs patch:
|
|
#
|
|
# Btrfs: send, don't delay dir move if there's a new parent inode
