From 89a4eb17deddba4ba8bfb0cf7c6801a608731f8c Mon Sep 17 00:00:00 2001 From: jhb Date: Tue, 13 May 2003 20:36:02 +0000 Subject: - Merge struct procsig with struct sigacts. - Move struct sigacts out of the u-area and malloc() it using the M_SUBPROC malloc bucket. - Add a small sigacts_*() API for managing sigacts structures: sigacts_alloc(), sigacts_free(), sigacts_copy(), sigacts_share(), and sigacts_shared(). - Remove the p_sigignore, p_sigacts, and p_sigcatch macros. - Add a mutex to struct sigacts that protects all the members of the struct. - Add sigacts locking. - Remove Giant from nosys(), kill(), killpg(), and kern_sigaction() now that sigacts is locked. - Several in-kernel functions such as psignal(), tdsignal(), trapsignal(), and thread_stopped() are now MP safe.
