Subject: [PATCH 01/11] libmount: don't use umount optimization for -l or -f
|
|
|
|
The options -l (lazy) and -f (force) means that the mountpoint may be
|
|
unreadable (for example because NFS server is unreadable). So we
|
|
should not try to be smart in this case and we should try to minimize
|
|
number of situations when stat() or readlink() is used for the
|
|
mountpoint.
