Subject: [PATCH 160/173] libmount: fix mnt_table_is_fs_mounted() for rbind
|
|
|
5113bc |
|
|
|
5113bc |
There is no difference between "bind" and "rbind" if we want to FS
|
|
|
5113bc |
root to search for the FS in mountinfo file.
|
|
|
5113bc |
|
|
|
5113bc |
fstab:
|
|
|
5113bc |
|
|
|
5113bc |
/dev/sdc1 /mnt/foo xfs defaults 0 0
|
|
|
5113bc |
/mnt/foo /mnt/test none rw,rbind 0 0
|
|
|
5113bc |
|
|
|
5113bc |
use -a more than once:
|
|
|
5113bc |
|
|
|
5113bc |
mount -a
|
|
|
5113bc |
mount -a
|
|
|
5113bc |
|
|
|
5113bc |
/proc/mounts (the current result):
|
|
|
5113bc |
|
|
|
5113bc |
/dev/sdc1 /mnt/foo xfs rw,relatime,attr2,inode64,noquota 0 0
|
|
|
5113bc |
/dev/sdc1 /mnt/test xfs rw,relatime,attr2,inode64,noquota 0 0
|
|
|
5113bc |
/dev/sdc1 /mnt/test xfs rw,relatime,attr2,inode64,noquota 0 0
|
|
|
5113bc |
/dev/sdc1 /mnt/foo xfs rw,relatime,attr2,inode64,noquota 0 0
|
|
|
5113bc |
|
|
|
5113bc |
expected (fixed version) result:
|
|
|
5113bc |
|
|
|
5113bc |
/dev/sdc1 /mnt/foo xfs rw,relatime,attr2,inode64,noquota 0 0
|
|
|
5113bc |
/dev/sdc1 /mnt/test xfs rw,relatime,attr2,inode64,noquota 0 0
