Subject: [PATCH 1/2] xfsdump: Revert "xfsdump: handle bind mount targets"
|
|
|
28dc94 |
|
|
|
28dc94 |
Bind mount mntpnts will be forbided in the next commits
|
|
|
28dc94 |
instead since it's not the real rootdir.
|
|
|
28dc94 |
|
|
|
28dc94 |
This cannot be reverted cleanly due to several cleanup
|
|
|
28dc94 |
patches, but the logic is reverted equivalently.
|
|
|
28dc94 |
|
|
|
28dc94 |
This reverts commit 25195ebf107dc81b1b7cea1476764950e1d6cc9d.
