[PATCH] uml - hostfs: avoid buffers
Use this: .set_page_dirty = __set_page_dirty_nobuffers, We already dropped the inclusion of <linux/buffer_head.h>, and we don't have a backing block device for this FS. "Without having looked at it, I'm sure that hostfs does not use buffer_heads. So setting your ->set_page_dirty a_op to point at __set_page_dirty_nobuffers() is a reasonable thing to do - it'll provide a slight speedup." This speedup is one less spinlock held and one less conditional branch, which isn't bad.
