From 91435650c233b93e0da389db74f4b2c11c5ad2d4 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Wed, 16 Feb 2011 13:10:41 -0500 Subject: Btrfs: put ENOSPC debugging under a mount option ENOSPC in btrfs is getting to the point where the extra debugging isn't required. I've put it under mount -o enospc_debug just in case someone is having difficult problems.
