Hi all, After merging the btrfs tree, today's linux-next build (x86_64 allmodconfig) failed like this: fs/btrfs/extent_io.c: In function 'btrfs_do_readpage': fs/btrfs/extent_io.c:3613:13: error: variable 'cur_end' set but not used [-Werror=unused-but-set-variable] 3613 | u64 cur_end; | ^~~~~~~ fs/btrfs/inode.c: In function 'btrfs_get_extent': fs/btrfs/inode.c:6872:32: error: unused variable 'io_tree' [-Werror=unused-variable] 6872 | struct extent_io_tree *io_tree = &inode->io_tree; | ^~~~~~~ Caused by commit a4ae8f42bbcf ("btrfs: remove unnecessary EXTENT_UPTODATE state in buffered I/O path") I have used the btrfs tree from next-20220819 for today. -- Cheers, Stephen Rothwell
