Add IOMAP_REPORT support to ext4, including support for inline data which iomap couldn't report so far. Switch to iomap_seek_{hole,data} on ext4. This patch set seems to be working correctly on ext4 as well as xfs under xfstests. Jan Kara has pointed out an issue that I can't reproduce though, so please review carefully.
