Subject: [PATCH 5/5] nfsd4: make set of large acl return efbig, not resource
Date: Mon, 24 Feb 2014 17:08:47 -0500	[thread overview]
Message-ID: <1393279727-29437-6-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <1393279727-29437-1-git-send-email-bfields@redhat.com>

From: "J. Bruce Fields" <bfields@redhat.com>

If a client attempts to set an excessively large ACL, return
NFS4ERR_FBIG instead of NFS4ERR_RESOURCE.  I'm not sure FBIG is correct,
but I'm positive RESOURCE is wrong (it isn't even a well-defined error
any more for NFS versions since 4.1).
