# FS QA Test No. btrfs/051

# Regression test for btrfs send where long paths (exceeding 230 characters)
# made send produce paths with random characters from a memory buffer returned
# by kmalloc, as send forgot to populate the new buffer with the path string.
#
# This issue is fixed by the following linux kernel btrfs patch:
#
# Btrfs: send, fix corrupted path strings for long paths
#
. ./common/preamble
_begin_fstest auto quick send
# Override the default cleanup function.
