From e87143ab89378a94307ba2abd777b39f31c545b0 Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Fri, 6 Jul 2012 03:31:33 -0600 Subject: [PATCH] Btrfs: do not abort transaction in prealloc case During disk balance, we prealloc new file extent for file data relocation, but we may fail in 'no available space' case, and it leads to flipping btrfs into readonly. It is not necessary to bail out and abort transaction since we do have several ways to rescue ourselves from ENOSPC case.
