autofs-5.1.6 - fix unlink mounts umount order

|
|
|
213b36 |
The recent changes to mount table handling to support the "ignore"
|
|
|
213b36 |
autofs pseudo option resulted in the incorrect umount order being used
|
|
|
213b36 |
in the unlink_mount_tree() function.
|
|
|
213b36 |
|
|
|
213b36 |
To fix this change unlink_mount_tree() to use the existing get_mnt_list()
|
|
|
213b36 |
function to construct a correctly ordered list for the umounts.
