The check script requires that it be run as root, so adding individualized checks for this in each teat is not needed. Signed-off-by: Theodore Ts'o <tytso@mit.edu> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dave Chinner <david@fromorbit.com>

# FS QA Test No. btrfs/058
|
|
#
|
|
# Regression test for a btrfs issue where we create a RO snapshot to use for
|
|
# a send operation which fails with a -ESTALE error, due to the presence of
|
|
# orphan inodes accessible through the snapshot's commit root but no longer
|
|
# present through the main root.
|
|
#
|
|
# This issue is fixed by the following linux kernel btrfs patch:
|
|
#
|
|
# Btrfs: update commit root on snapshot creation after orphan cleanup
