common: use fiemap to count extents and holes
For the follwoing tests, this patch adds general script to get extent and hole counts. xfs/137 (data vs filesize) xfs/138 (data vs filesize vs truncate) xfs/139 (data vs filesize vs partial truncate) xfs/140 (data vs filesize vs extending truncate) xfs/179 (data vs filesize w/ fsync) xfs/180 (data vs filesize w/ sync) xfs/182 (data vs filesize w/ recovery) It also requires these tests to check for fiemap support.
