[Cluster-devel] [PATCH v2 0/6] SEEK_HOLE / SEEK_DATA via iomap

[Andreas Gruenbacher]

These patches, on top of the page_cache_seek_hole_data patches posted earlier
today, convert xfs to implement SEEK_HOLE / SEEK_DATA via iomap, and implement
SEEK_HOLE / SEEK_DATA via iomap in gfs2.

ext4 doesn't implement IOMAP_REPORT, so it can't be switched to use the iomap
based SEEK_HOLE / SEEK_DATA or fiemap code so far.

Thanks,
Andreas
