no need to have that one if you implement aio_read -> use do_sync_read

readv and aio_read are just wrappers around this one.

pretty trivial

just use do_sync_write

you don't need all these.  Just writev and aio_write as wrappers around a common one

this one doesn't share code anyway

unless you want to implement a readonly filesystem with xip support you
don't need this one.
