Hi all,

this series removes generic_writepages by open coding the current
functionality in the three remaining callers. Besides removing some
code the main benefit is that one of the few remaining ->writepage
callers from outside the core page cache code go away.

Note that testing has been a bit limited - ntfs3 does not seem to
be supported by xfstests at all, and xfstests on ocfs2 is a complete
shit show even for the base line.
