Subject: [PATCH] knfsd: fix spurious EINVAL errors on first access of
new filesystem
References: 340873

The v2/v3 acl code in nfsd is translating any return from fh_verify() to
nfserr_inval. This is particularly unfortunate in the case of an
nfserr_dropit return, which is an internal error meant to indicate to
callers that this request has been deferred and should just be dropped
pending the results of an upcall to mountd.

Thanks to Roland <[email protected]> for bug report and data collection.
