cifs: convert cifs_iovec_read to use async reads
Convert cifs_iovec_read to use async I/O. This also raises the limit on the rsize for uncached reads. We first allocate a set of pages to hold the replies, then issue the reads in parallel and then collect the replies and copy the results into the iovec. A possible future optimization would be to kmap and inline the iovec buffers and read the data directly from the socket into that. That would require some rather complex conversion of the iovec into a kvec however. Signed-off-by: Jeff Layton <jlayton@redhat.com>
