hi currently in exit1() we call acct_process() with Giant held. I looked at the code and I think this is because of tty need for Giant locking. Because of this we have to release process limit in a separate PROC_LOCK()/UNLOCK() block.
my just-to-look-at patch does this 1) moves the acct_process() in exit1() out of Giant locked block (upward) 2) acquires Giant in the acct_process() around tty handling 3) moves the p->p_limit to a different PROC_LOCK/UNLOCK block (upward) the result is saving 2 proc mtx operations in exit1() can you look at it and tell me if its correct or wrong or something like that? if it's correct is it worth committing? saving two mtx operations is a nice thing :) thank you roman _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
