[PATCH 11/13] xfs_repair: set *parent if process_dir2_data() fixes root inode

[Eric Sandeen]

process_dir2_data() may fix the root dir's parent inode:

"bad .. entry in root directory inode 6912, was 7159: correcting"

But we don't update the *parent passed in in that case; this then leads to
an assert later in process_dir2:

xfs_repair: dir2.c:2039: process_dir2:
  Assertion `(ino != mp->m_sb.sb_rootino && ino != *parent) ||
  (ino == mp->m_sb.sb_rootino && (ino == *parent || need_root_dotdot == 1))'
  failed.

Updating the value of *parent when we fix the parent value resolves this
problem.
