[PATCH 02/11] xfs: return committed status from xfs_trans_roll()

Brian Foster
2015-08-06T17:44:36Z

Some callers need to make error handling decisions based on whether the
current transaction successfully committed or not. Rename
xfs_trans_roll(), add a new parameter and provide a wrapper to preserve
existing callers.
