xfs_repair: Fix root inode's parent when it's bogus for sf directory
|
|
|
89952e |
|
|
|
89952e |
Currently when root inode is in short-form and its parent ino
|
|
|
89952e |
has an invalid value, process_sf_dir2() ends up not fixing it,
|
|
|
89952e |
because if verify_inum() fails we never get to the next case which
|
|
|
89952e |
would fix the root inode's parent pointer.
|
|
|
89952e |
|
|
|
89952e |
This behavior triggers the following assert on process_dir2():
|
|
|
89952e |
|
|
|
89952e |
ASSERT((ino != mp->m_sb.sb_rootino && ino != *parent) ||
|
|
|
89952e |
(ino == mp->m_sb.sb_rootino &&
|
|
|
89952e |
(ino == *parent || need_root_dotdot == 1)));
|
|
|
89952e |
|
|
|
89952e |
This patch fixes this behavior by making sure we always properly
|
|
|
89952e |
handle rootino parent pointer in process_sf_dir2()
