[PATCH 0/9 V6] New ->fiemap infrastructure and ->bmap removal

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi.

This is the 6th version of the complete series with the goal to deprecate and
eventually remove ->bmap() interface, in lieu if FIEMAP.

This V6, compared with the previous one, is rebased agains next-20190904, and
addresses a few issues found by kbuild test robot, and other points discussed in
previous version.

Detailed information are in each patch description, but the biggest change
in this version is the removal of FIEMAP_KERNEL_FIBMAP flag in patch 8, so,
reducing patch's complexity and avoiding any specific filesystem modification.

The impact of such change is further detailed in patch 8.

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
