ceph: switch to ->read_iter()

start adding the tag to iov_iter

2014-05-06T21:32:49+00:00

For now, just use the same thing we pass to ->direct_IO() - it's all
iovec-based at the moment.  Pass it explicitly to iov_iter_init() and
account for kvec vs. iovec in there, by the same kludge NFS ->direct_IO()
uses.

new helper: generic_file_read_iter()

2014-05-06T21:32:49+00:00

iov_iter-using variant of generic_file_aio_read().  Some callers
converted.  Note that it's still not quite there for use as ->read_iter() -
we depend on having zero iter->iov_offset in O_DIRECT case.  Fortunately,
that's true for all converted callers (and for generic_file_aio_read() itself).

ceph_aio_read(): keep iov_iter across retries

kill generic_segment_checks()

2014-05-06T21:32:43+00:00

all callers of ->aio_read() and ->aio_write() have iov/nr_segs already
checked - generic_segment_checks() done after that is just an odd way
to spell iov_length().

kill iov_iter_copy_from_user()

2014-05-06T21:32:42+00:00

all callers can use copy_page_from_iter() and it actually simplifies
them.
