[PATCH 0/3] implement readpages() for block device to optimize sequential read

2014-08-05 Thread Akinobu Mita
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
