Subject: [PATCH] kernel/futex.c: Uneeded memory barrier
Date: Fri, 12 Sep 2003 15:20:17 -0300	[thread overview]
Message-ID: <3F620E61.4080604@terra.com.br> (raw)

	Hi Rusty,

	Patch against 2.6-test5.

	Kills an unneeded set_current_state after schedule_timeout, since it 
already guarantees that the task will be TASK_RUNNING.

	Also, when setting the state to TASK_RUNNING, isn't that memory 
barrier unneeded? Patch removes this memory barrier too.

	If it looks good, please consider applying.

	Thanks.

Felipe
