From 3d3a126a81f152a5abfe19916a5099d2bbd38f9d Mon Sep 17 00:00:00 2001 From: David Sterba Date: Fri, 10 Feb 2017 19:23:20 +0100 Subject: [PATCH] btrfs: remove unused parameter from btrfs_check_super_valid None of the checks need to know the ro/rw status as they're all not changing the superblock. Moreover, we can access the sb flags directly if we'd need to decide by the ro/rw status.
