From: Arnd Bergmann <arnd@arndb.de>
The only user of pages_processed was removed, so it's now a local write-only variable that can be eliminated as well:
fs/btrfs/extent_io.c:214:16: error: variable 'pages_processed' set but not used [-Werror,-Wunused-but-set-variable]
Fixes: 9480af8687200 ("btrfs: split page locking out of __process_pages_contig") Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202307241541.8w52nEnt-lkp@intel.com/ Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- fs/btrfs/extent_io.c | 2 -- 1 file changed, 2 deletions(-)
