Subject: [PATCH 06/16] vfs: Rename generic_file_aio_write_nolock

generic_file_aio_write_nolock() is now used only by block devices and raw
character device. Filesystems should use __generic_file_aio_write() in case
generic_file_aio_write() doesn't suit them. So rename the function to
device_aio_write().
