From: Oleg Nesterov Date: Sun, 30 Oct 2005 23:03:46 +0000 (-0800) Subject: [PATCH] remove unneeded SI_TIMER checks X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ae6866c377943de73e2c95398ff0120516f167ce;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [PATCH] remove unneeded SI_TIMER checks This patch removes checks for ->si_code == SI_TIMER from send_signal, specific_send_sig_info, __group_send_sig_info. I think posix-timers.c used these functions some time ago, now it sends signals via send_{,group_}sigqueue, so these hooks are unneeded.
