[PATCH 0/2] xfs: fix CoW fork repair error handling

[Yingjie Gao]

Hi all,

This series fixes two error handling bugs in the CoW fork repair code.

The non-realtime helper can lose real failures in two different ways:
it returns success after the common cleanup labels, and the
force-rebuild path can return directly without freeing the AG repair
context.

The realtime helper has a related cleanup bug in its force-rebuild
path.  If marking the full mapping fails, the code jumps past the
rtgroup scrub cleanup and only drops the local rtgroup reference.

Split the fixes into two patches so that the non-RT and RT changes
remain easy to review and bisect independently.

Patches in this series:
  1. fix non-RT CoW fork repair error returns and cleanup
  2. fix RT CoW fork repair cleanup

Thanks,
Yingjie
