[PATCH v2 0/2] ocfs2: clean up falloc and inode flag definitions

[Anthony Iliopoulos]

This short series cleans up and replaces redundant ocfs2-specific falloc
ioctl and inode flag definitions in favor of generic ones.

v2:
- repost as series
- replace previously omitted OCFS2_FL_{MODIFIABLE,VISIBLE}

  ocfs2: replace ocfs2-specific falloc ioctls with generic ones
  ocfs2: replace ocfs2-specific inode flags with generic ones

[PATCH v2 1/2] ocfs2: replace ocfs2-specific falloc ioctls with generic ones

[Anthony Iliopoulos]

Replace custom ocfs2 space reservation structures and ioctl definitions
with the generic file space allocation interfaces.

Those were originally copied from xfs in commit b25801038da5 ("ocfs2:
Support xfs style space reservation ioctls") for compatibility reasons,
which were eventually lifted to vfs and made generic. As such there is
no reason to carry around the redundant definitions any longer, they can
be dropped at this point.

[PATCH v2 2/2] ocfs2: replace ocfs2-specific inode flags with generic ones

[Anthony Iliopoulos]

The ocfs2 inode flag macros are alias definitions for the generic fs
flags. Remove these redundant macros, most of which are anyway unused,
and use the generic flags directly.
