Mateusz Guzik a8c8e44bf0 vfs: manage mnt_ref with atomics ... New primitive is introduced to denote sections can operate locklessly on aspects of struct mount, but which can also be disabled if necessary. This provides an opportunity to start scaling common case modifications while providing stable state of the struct when facing unmount, write suspendion or other events. mnt_ref is the first counter to start being managed in this manner with the intent to make it per-cpu.
