Chris Mason 3435302953 Btrfs: Fix race against disk_i_size updates ... The code to update the on disk i_size happens before the ordered_extent record is removed. So, it is possible for multiple ordered_extent completion routines to run at the same time, and to find each other in the ordered tree. The end result is they both decide not to update disk_i_size, leaving it too small. This temporary fix just puts the updates inside the extent_mutex. A real solution would be stronger ordering of disk_i_size updates against removing the ordered extent from the tree. Signed-off-by: Chris Mason <chris.mason@oracle.com>		2008-09-25 11:04:07 -04:00
