From b31eabd86eb68d3c217e6821078249bc045e698a Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Mon, 31 Jan 2011 16:48:24 -0500 Subject: Btrfs: catch errors from btrfs_sync_log btrfs_sync_log returns -EAGAIN when we need full transaction commits instead of small log commits, but sometimes we were dropping the return value. In practice, we check for this a few different ways, but this is still a bug that can leave off full log commits when we really need them.
