shared memory and semaphores,interresting tidbit on Linux (2.4.0-test
series at least) is that shared memory can be a nodev filesystem (like proc or
devfs):
/dev/ide/host0/bus0/target0/lun0/part2 on / type ext2 (rw,errors=remount-ro,errors=remount-ro)
proc on /proc type proc (rw)
/shm on /shm type shm (rw)
and there's at least a few other nodev filesystem in the latest kernel
series:
nodev shm
nodev sockfs
nodev pipefs
nodev proc
ext2
nodev devfs
i'm doing some heavy research into these filesystem but so far,there's a
BIG lack of docs.
