The shmfs currently sets the filesystem ID to zero (function
shm_statfs in ipc/shm.c). This makes it hard/impossible to be 100%
sure the file one creates is on a shmfs filesystem. Of course we
could define the super magic for the shmfs as 0 but please let there
be a constant SHMFS_SUPER_MAGIC.
The problem arises when in the libc I'm using open() and have to make
sure the file handle I get really belongs to a file on the shmfs and
not a file on a real filesystem.
Thanks,
