[v2,0/7] More buffer_head cleanups

Message

The first patch is a left-over from last cycle.  The rest fix "obvious"
block size > PAGE_SIZE problems.  I haven't tested with a large block
size setup (but I have done an ext4 xfstests run).

v2:
 - Pick up R-b tags from Pankaj
 - Use div_u64() instead of a raw divide.  Thanks, i386.
 - Add a patch for __block_write_begin_int(), spotted by Ryusuke Konishi
 - That inspired the seventh patch which finally eliminates block_size_bits().

Matthew Wilcox (Oracle) (7):
  buffer: Return bool from grow_dev_folio()
  buffer: Calculate block number inside folio_init_buffers()
  buffer: Fix grow_buffers() for block size > PAGE_SIZE
  buffer: Cast block to loff_t before shifting it
  buffer: Fix various functions for block size > PAGE_SIZE
  buffer: Handle large folios in __block_write_begin_int()
  buffer: Fix more functions for block size > PAGE_SIZE
