From 779880ef35b60ac82eed1dcaec6db5b34a170df8 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Thu, 31 Jan 2013 14:30:08 -0500 Subject: [PATCH] Btrfs: fix how we discard outstanding ordered extents on abort When we abort we've been just free'ing up all the ordered extents and hoping for the best. This results in lots of warnings from various places, warnings from btrfs_destroy_inode() because it's ENOSPC accounting isn't fixed. It will also screw up lots of pages who have been set private but never get cleared because the ordered extents are never allowed to be submitted. This patch fixes those warnings.
