Christoph Hellwig	e0ec0a6ba6	gfs2: remove the unused gfs2_stuffed_write_end function ... This function was overlooked when the write_begin and write_end address space operations were removed as part of gfs2's iomap conversion.

Andreas Gruenbacher	64bc06bb32	gfs2: iomap buffered write support ... With the traditional page-based writes, blocks are allocated separately for each page written to. With iomap writes, we can allocate a lot more blocks at once, with a fraction of the allocation overhead for each page. Split calculating the number of blocks that can be allocated at a given position (gfs2_alloc_size) off from gfs2_iomap_alloc: that size determines the number of blocks to allocate and reserve in the journal.
