321 mnt->mnt_count324 ``mnt_count`` is a per-CPU reference counter on "``mount``" structures.327 it needs to check with every CPU. Taking a ``mnt_count`` reference330 ``mnt_count`` doesn't ensure that the mount remains in the namespace and,334 filesystem. So a reference through ``->mnt_count`` provides a stable347 the ``mnt_count``. Finally the value in ``mount_lock`` is checked against349 was a change, the ``mnt_count`` is decremented and the whole process is395 step. A reference through ``d_lockref`` and ``mnt_count`` is always867 For ``mnt->mnt_count`` it is safe to take a reference as long as
