H A Dobjects.cdiff 2de160417315b8d64455fe03e9bb7d3308ac3281 Thu Jan 20 15:55:46 CST 2022 David Howells <dhowells@redhat.com> netfs: Change ->init_request() to return an error code

Change the request initialisation function to return an error code so that
the network filesystem can return a failure (ENOMEM, for example).

This will also allow ceph to abort a ->readahead() op if the server refuses
to give it a cap allowing local caching from within the netfslib framework
(errors aren't passed back through ->readahead(), so returning, say,
-ENOBUFS will cause the op to be aborted).
