There will be a merge conflict between "fscrypt: cache decrypted symlink target
in ->i_link", and "ext4: make use of ->free_inode()" and "f2fs: switch to
->free_inode()".  The correct resolutions should be fairly straightforward:

	static void ext4_free_in_core_inode(struct inode *inode)
	{
		fscrypt_free_inode(inode);
		kmem_cache_free(ext4_inode_cachep, EXT4_I(inode));
	}

and

	static void f2fs_free_inode(struct inode *inode)
	{
		fscrypt_free_inode(inode);
		kmem_cache_free(f2fs_inode_cachep, F2FS_I(inode));
	}
