I have a simple lock LKM which in essence allows processes to 1) test a lock 2) drop into kernel sleep() if it's set 3) if it's not set, lock it using pentium cswap 4) when clearing it, if there was contention, syscall that does a wakeup() it's very efficient, much more so than sysv semaphores. If you want it let me know. It's called fastlock. ron Ron Minnich |"Inferno runs on MIPS ..., Intel ..., and AMD's rminnich@sarnoff.com |29-kilobit-per-second chip-based architectures ..."
