This makes it easier to convert to using the netfs library for VM write hooks. Changes ======= ver #3: - Move the patch to make ceph_netfs_issue_op() before this one so that reading inline data is handled there. - Call read_mapping_folio() to allocate and cause the page to be read instead of reading inline data directly there. - Assume that we can just dump the uninlined data into the pagecache, no matter the caps. ver #2: - Removed the uninline-handling code from ceph_write_begin() also.
