This patchset implements readpages() operation for block device by
using mpage_readpages() which can create multipage BIOs instead of
BIOs for each page and reduce system CPU time consumption.

Akinobu Mita (3):
  vfs: make guard_bh_eod() more generic
  vfs: guard end of device for mpage interface
  block_dev: implement readpages() to optimize sequential read
