Message

Hi.

This is the 5th version of the complete series with the goal to deprecate and
eventually remove ->bmap() interface, in lieu of FIEMAP.

This V5, compared with V4 is properly rebased against 5.3, and addresses the
issues raised in V4 discussion.

Details of what changed on each patch are in their specific changelogs.



Carlos Maiolino (9):
  fs: Enable bmap() function to properly return errors
  cachefiles: drop direct usage of ->bmap method.
  ecryptfs: drop direct calls to ->bmap
  fibmap: Use bmap instead of ->bmap method in ioctl_fibmap
  fs: Move start and length fiemap fields into fiemap_extent_info
  iomap: Remove length and start fields from iomap_fiemap
  fiemap: Use a callback to fill fiemap extents
  Use FIEMAP for FIBMAP calls
  xfs: Get rid of ->bmap
