the first two patches are fine with me, they're basically my patches with the bugs fixed and the missing conversions done, so they must be good ;-)
can't really comment on the third one because I don't understand the aio internals good enough.
Onced this goes to -mm we should add a third patch to kill generic_file_read/generic_file_write and convert all filesystems to the aio/vectored variant and use do_sync_read/do_sync_write for .read/.write. The major syscalls use the aio_ variant directly anyway, this is only needed for some special cases like the ELF loader. Removing generic_file_read/generic_file_write will finally cut filemap.c back to a sane size.
