The patch titled
Streamline generic_file_* interfaces and filemap cleanups
has been removed from the -mm tree. Its filename is
streamline-generic_file_-interfaces-and-filemap.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: Badari Pulavarty <pbadari@xxxxxxxxxx>
Clean up generic_file_*_read/write() interfaces. Christoph Hellwig gave me
the idea for this clean ups.
In a nutshell, all filesystems should set .aio_read/.aio_write methods and use
do_sync_read/ do_sync_write() as their .read/.write methods. This allows us
to cleanup all variants of generic_file_* routines.
Final available interfaces:
generic_file_aio_read() - read handler
generic_file_aio_write() - write handler
generic_file_aio_write_nolock() - no lock write handler
__generic_file_aio_write_nolock() - internal worker routine
