# FS QA Test 206
#
# Validate that without no-holes we do not get a i_size that is after a gap in
# the file extents on disk when punching a hole past i_size. 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
# Import common functions.
. ./common/filter
. ./common/dmlogwrites
