This patch results in the following code in fs/btrfs/disk-io.c:open_ctree():

	struct btrfs_super_block *disk_super;
	... (no access to disk_super)
	btrfs_info(fs_info, "first mount of filesystem %pU", disk_super->fsid);

which I would assume _should_ result in btrfs crashes. No idea why that isn't
actually happening or why gcc doesn't complain. Building allmodconfig with
clang does complain, but doesn't bail out.

s/btrfs/disk-io.c:2832:55: warning: variable 'disk_super' is uninitialized when used here [-Wuninitialized]
         btrfs_info(fs_info, "first mount of filesystem %pU", disk_super->fsid);
                                                              ^~~~~~~~~~

The actual log output is:

[    7.302427] BTRFS info (device nvme0n1): first mount of filesystem (efault)

It might be a good idea to either revert this patch or fix it up
(though I don't know how to fix it up).

yeah, that doesn't look good, now reverted, thanks!
