[PATCH 00/13] Make btrfs W=1 clean

[Nikolay Borisov <nborisov@suse.com>]

Hello,

This patch series aims to fix all current warnings produced by compiling btrfs
with W=1. My hopes are with these additions W=1 can become a default build
options for btrfs. With this series applied misc-next currently produces 1
genuine warning for an unused variable:

fs/btrfs/zoned.c: In function ‘btrfs_sb_log_location_bdev’:
fs/btrfs/zoned.c:491:6: warning: variable ‘zone_size’ set but not used [-Wunused-but-set-variable]
  491 |  u64 zone_size;


But I haven't fixed it since it's part of the WIP zoned support.
