[PATCH] AIO support for raw/O_DIRECT
Patch from Badari Pulavarty <pbadari@us.ibm.com> and myself
This patch adds the infrastructure for performing asynchronous (AIO) blockdev
direct-IO.
- Adds generic_file_aio_write_nolock() and make other
generic_file_*_write() to use it.
- Modify generic_file_direct_IO() and ->direct_IO() functions to take
"kiocb *" instead of "file *".
- Renames generic_direct_IO() to blockdev_direct_IO().
- Move generic_file_direct_IO() to mm/filemap.c (it is not
blockdev-specific, whereas the rest of fs/direct-io.c is).
- Add AIO read/write support to the raw driver.
