From: Alan Stern Date: Sat, 28 Oct 2006 17:38:58 +0000 (-0700) Subject: [PATCH] workqueue: update kerneldoc X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=057647fc47b3a5fbcfa997041db3f483d506603c;p=linux-beck.git [PATCH] workqueue: update kerneldoc This patch (as812) changes the kerneldoc comments explaining the return values from queue_work(), queue_delayed_work(), and queue_delayed_work_on(). The updated comments explain more accurately the meaning of the return code and avoid suggesting that a 0 value means the routine was unsuccessful.
