Subject: linux-next: build failure after merge of the vfs tree

Hi Al,

After merging the vfs tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/nilfs2/inode.c: In function 'nilfs_clear_inode':
fs/nilfs2/inode.c:630: error: implicit declaration of function 'nilfs_btnode_cache_clear'

Caused by commit 743a0a2f1a89e53d656ec6a2f715111d92642bcb ("convert
nilfs2 to ->evict_inode()") interacting with commit
ceb4f9c819c321e7eabf53b51f956ff959561573 ("nilfs2: get rid of
nilfs_bmap_union") from the nilfs2 tree which removed the implicit
inclusion of btnode.h (via bmap_union.h via nilfs.h).

I have added the following patch for today (which should be applied to
the vfs tree or merged into the above vfs tree commit):

Subject: [PATCH] nilfs2: inode.c needs to include btnode.h directly now

Due to the new usage of nilfs_btnode_cache_clear().
