# FS QA Test No. btrfs/040
|
|
#
|
|
# Regression test for btrfs incremental send issue where an rmdir
|
|
# instruction was sent multiple times for the same target directory.
|
|
# The number of times depended on the number of hardlinks against
|
|
# the same inode inside the target directory. That inode must have
|
|
# had the highest number of all the inodes that were children of the
|
|
# directory. This made the btrfs receive command fail immediately once
|
|
# it received the second rmdir instruction.
|
|
#
|
|
# This issue is fixed by the following linux kernel btrfs patch:
|
|
#
|
|
# Btrfs: send, don't send rmdir for same target multiple times
|
|
