From 045f902de5a6eb5927c0f092c38be7a381f634f0 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Tue, 16 Oct 2007 23:26:47 -0700 Subject: [PATCH] do_sigaction: remove now unneeded recalc_sigpending() With the recent changes, do_sigaction()->recalc_sigpending_and_wake() can never clear TIF_SIGPENDING. Instead, it can set this flag and wake up the thread without any reason. Harmless, but unneeded and wastes CPU.
