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/030
|
|
#
|
|
# Regression test for btrfs' incremental send feature:
|
|
#
|
|
# 1) Create several nested directories;
|
|
# 2) Create a read only snapshot;
|
|
# 3) Change the parentship of some of the deepest directories in a reverse
|
|
# way, so that parents become children and children become parents;
|
|
# 4) Create another read only snapshot and use it for an incremental send
|
|
# relative to the first snapshot.
|
|
#
|
|
# At step 4 btrfs' send entered an infinite loop, increasing the memory it
|
|
# used while building path strings until a krealloc was unable to allocate
|
|
# more memory, which caused a warning dump in dmesg.
