fs/btrfs/extent_io.c:3959:34: error: ‘tree’ undeclared (first use in this function); did you mean ‘true’?
3959 | struct btrfs_fs_info *fs_info = tree->fs_info;
| ^~~~
| true
fs/btrfs/extent_io.c:3959:34: note: each undeclared identifier is reported only once for each function it appears in
make[2]: *** [scripts/Makefile.build:268: fs/btrfs/extent_io.o] Error 1
make[1]: *** [scripts/Makefile.build:505: fs/btrfs] Error 2
