Hi Andrew, After merging the akpm tree, today's linux-next build (x86_64 allmodconfig) failed like this:
fs/gfs2/rgrp.c: In function 'gfs2_rs_alloc':
fs/gfs2/rgrp.c:456:2: error: implicit declaration of function 'rb_init_node'
[-Werror=implicit-function-declaration]
Caused by commit 5599fe1ab023 ("rbtree: empty nodes have no color") from
the akpm tree interacting with commit cde7c325077b ("GFS2: Add structure
to contain rgrp, bitmap, offset tuple") from the gfs2 tree.
I have applied the following merge fix patch (which is probably not
sufficient).
