From 9c199b63acd05fde0449cb27100b139d3ad1e3ce Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 14 Sep 2012 13:58:59 -0400 Subject: [PATCH] Btrfs: don't do anything in our ->freeze_fs and ->unfreeze_fs We do not need to do anything special to freeze or unfreeze, it's all taken care of by the generic work, and what we currently have is wrong anyway since we shouldn't be returnning to userspace with mutexes held anyway.
