[PATCH 00/11] splice cleanups

[Miklos Szeredi <mszeredi@redhat.com>]

This contains assorted cleanups in the splice area:

 - add helpers for pipe buf ops instead of directly calling them

 - page cache buf doesn't seem to need confirming (since ages)

 - generic_file_splice_read() and generic_file_read() have lots of
   duplication

Git tree is here:

Thanks,
Miklos
