From d41d23033a88a4797ffea69d29754fe85962ca1f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 9 Jan 2017 20:18:47 -0600 Subject: [PATCH] xfs: remove prev argument to xfs_bmapi_reserve_delalloc Source kernel commit: 65c5f419788d623a0410eca1866134f5e4628594 We can easily lookup the previous extent for the cases where we need it, which saves the callers from looking it up for us later in the series.
