From dcd497f99a1ef29a7c5e76142965be77e9dacabd Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Thu, 23 Jun 2005 00:09:07 -0700 Subject: [PATCH] streamline preempt_count type across archs The preempt_count member of struct thread_info is currently either defined as int, unsigned int or __s32 depending on arch. This patch makes the type of preempt_count an int on all archs. Having preempt_count be an unsigned type prevents the catching of preempt_count < 0 bugs, and using int on some archs and __s32 on others is not exactely "neat" - much nicer when it's just int all over. A previous version of this patch was already ACK'ed by Robert Love, and the only change in this version of the patch compared to the one he ACK'ed is that this one also makes sure the preempt_count member is consistently commented.
