1) _require_fiemap and _require_xfs_io_command "fiemap" do the same thing, but some test cases use the former and some use the latter, so i feel they should be unified. 2) The number of helpers like this is slowly growing, but it's easy to simply use _require_xfs_io_command directly and just specify the command we want to check. This is just a cleanup for keeping it simple. Signed-off-by: Xiao Yang <yangx.jy@cn.fujitsu.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

# fallocate/truncate tests with FALLOC_FL_KEEP_SIZE option.

# Verify if the disk space is released after truncating a file to i_size after
|
|
# writing to a portion of a preallocated range.
|
|
#
|
|
# This also verifies that truncat'ing up past i_size doesn't remove the
|
|
# preallocated space.
