From 7dc102b737e9f49dac426161294cb2d326a97d8e Mon Sep 17 00:00:00 2001 From: Sunil Mushran Date: Tue, 3 Feb 2009 12:37:13 -0800 Subject: ocfs2/dlm: Retract fix for race between purge and migrate Mainline commit d4f7e650e55af6b235871126f747da88600e8040 attempts to delay the dlm_thread from sending the drop ref message if the lockres is being migrated. The problem is that we make the dlm_thread wait for the migration to complete. This causes a deadlock as dlm_thread also participates in the lockres migration process. A better fix for the original oss bugzilla#1012 is in testing.
