From 1606283622689bdc460052b4a1281c36de13fe49 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 6 Feb 2013 18:04:53 -0800 Subject: [PATCH] workqueue: cosmetic update in try_to_grab_pending() With the recent is-work-queued-here test simplification, the nested if() in try_to_grab_pending() can be collapsed. Collapse it. This patch is purely cosmetic.
