Subject: [PATCH 2/2] nfsd: return ENOSPC if unable to allocate a session slot
Date: Thu, 21 Jun 2018 16:35:33 +0000	[thread overview]
Message-ID: <1529598933-16506-2-git-send-email-manjunath.b.patil@oracle.com> (raw)
In-Reply-To: <1529598933-16506-1-git-send-email-manjunath.b.patil@oracle.com>

Presently nfserr_jukebox is being returned by nfsd for create_session
request if server is unable to allocate a session slot. This may be
treated as NFS4ERR_DELAY by the clients and which may continue to re-try
create_session in loop leading NFSv4.1+ mounts in hung state. nfsd
should return nfserr_nospc in this case as per rfc5661(section-18.36.4
subpoint 4. Session creation).
