From 360e1a534901592b289ba8768fc71b6e6ad49070 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 4 Jan 2013 12:50:30 -0500 Subject: SUNRPC: Partial revert of commit 168e4b39d1afb79a7e3ea6c3bb246b4c82c6bdb9 Partially revert commit (SUNRPC: add WARN_ON_ONCE for potential deadlock). The looping behaviour has been tracked down to a knownn issue with workqueues, and a workaround has now been implemented.
