From eece6a9cf69140fe1886f14d9a96add4f9929d78 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Fri, 10 Feb 2017 19:04:32 +0100 Subject: [PATCH] btrfs: merge two superblock writing helpers write_all_supers and write_ctree_super are almost equal, the parameter 'trans' is unused so we can drop it and have just one helper.
