The expire code uses the list of mounts to decide if additional expire
|
|
|
4d476f |
check requests should be sent to the kernel. This doesn't take into
|
|
|
4d476f |
account the possibility there could be symlinks that might be able to
|
|
|
4d476f |
be expired.
|
|
|
4d476f |
|
|
|
4d476f |
count_mounts() does count symlinks so use that only when working out
|
|
|
4d476f |
how many expire requests should be sent.
