From 8f3b65a3d66bcc086e1eb040b7545e70681f2ed1 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Thu, 15 Dec 2011 09:29:43 -0500 Subject: [PATCH] Btrfs: add a cond_resched() into the worker loop If we have a constant stream of end_io completions or crc work, we can hit softlockup messages from the async helper threads. This adds a cond_resched() into the loop to avoid them.
