# FS QA Test 172
#
# Validate that without no-holes we do not get an i_size that is after a gap in
# the file extents on disk. This is fixed by the following patches
#
# btrfs: use the file extent tree infrastructure
# btrfs: replace all uses of btrfs_ordered_update_i_size
#
. ./common/preamble
_begin_fstest auto quick log replay recoveryloop
# Import common functions.
. ./common/filter
. ./common/dmlogwrites
# real QA test starts here
# Modify as appropriate.
