[PATCH 0/5] Refactor ioctl_fibmap() internal interface

[Carlos Maiolino <cmaiolino@redhat.com>]

Hi,

This series refactor the internal structure of FIBMAP so that the filesystem can
properly report errors back to VFS, and also simplifies its usage by
standardizing all ->bmap() method usage via bmap() function.

The last patch is a bug fix for ioctl_fibmap() calls with negative block values.



This patchset is essentially a part of the original series reworking FIEMAP to
also be used for FIBMAP calls.

Due the fact the original series makes too many changes, I decided to split it
into smaller series, so they can be reviewed and applied individually, with
specific purposes, instead of changing everything in a single set. I believe
this makes the review process for this work easier too.

Cheers.

Carlos Maiolino (5):
  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
  fibmap: Reject negative block numbers
