Miao Xie 5c39da5b6c Btrfs: do not delete a subvolume which is in a R/O subvolume ... Step to reproduce: # mkfs.btrfs <disk> # mount <disk> <mnt> # btrfs sub create <mnt>/subv0 # btrfs sub snap <mnt> <mnt>/subv0/snap0 # change <mnt>/subv0 from R/W to R/O # btrfs sub del <mnt>/subv0/snap0 We deleted the snapshot successfully. I think we should not be able to delete the snapshot since the parent subvolume is R/O. Signed-off-by: Miao Xie <miaox@cn.fujitsu.com>		2013-01-14 13:52:32 -05:00
