The discard_partial_page_buffers is no longer used anywhere so we can
simply remove it including the *_no_lock variant and

Hi,
This set of patches are aimed to allow truncate_inode_pages_range() handle
ranges which are not aligned at the end of the page. Currently it will
hit BUG_ON() when the end of the range is not aligned. Punch hole feature
however can benefit from this ability saving file systems some work not
fo
->invalidatepage() aop now accepts range to invalidate so we can make
use of it in all ext4 invalidatepage routines.

is should also fix theoretical race on waitqueue while
using simultaneously wait_event_lock_irq() and wait_event() because of
lack of locking around current state setting and wait queue removal.

Since the 'end' semantic is the same in several functions there this
commit just fixes the condition to use the 'end' variable correctly in
that context.
