[PATCH 0/2] nfsd: don't use the xdr buf for temporary storage in CB_NOTIFY

[Jeff Layton <jlayton@kernel.org>]

I posted a patch to fix up a sparse warning with a cast a few days ago
[1], but Chuck objected and wanted to fix this by moving these
(host-endian) allocations out of the xdr stream entirely.

This patchset should do that. Some of them are able to be moved to
temporary stack allocations, but the mask fields need a separate
kmalloc'ed field tracked in struct nfsd4_cb_notify.

Please consider these for v7.4.
