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/047
|
|
#
|
|
# Verify that after an incremental btrfs send the replicated file has
|
|
# the same exact hole and data structure as in the origin filesystem.
|
|
# This didn't use to be the case before the send stream version 2 -
|
|
# holes were sent as write operations of 0 valued bytes instead of punching
|
|
# holes with the fallocate system call, and pre-allocated extents were sent
|
|
# as well as write operations of 0 valued bytes instead of intructions for
|
|
# the receiver to use the fallocate system call. Also check that prealloc
|
|
# extents that lie beyond the file's size are replicated by an incremental
|
|
# send.
|
|
#
|
|
# More specifically, this structure preserving guarantee was added by the
|
|
# following linux kernel commits:
|
|
#
|
|
# Btrfs: send, use fallocate command to punch holes
|
|
# Btrfs: send, use fallocate command to allocate extents
