◆ fs

filesystem_t* superblock_t::fs

◆ mountCount

atomic_uint64_t superblock_t::mountCount

The number of mounts of this superblock.

Note that this does need to be separate from the reference count as a superblock is referenced by mounts, but it can also be referenced by other things like open files.
