Subject: [PATCH 02/28] staging/lustre/llite: correct request handling after ll_lookup_it()
Date: Sun, 19 Jun 2016 22:07:17 -0400 [thread overview]
Message-ID: <1466388463-1817551-3-git-send-email-green@linuxhacker.ru> (raw)
In-Reply-To: <1466388463-1817551-1-git-send-email-green@linuxhacker.ru>
From: "John L. Hammond" <john.hammond@intel.com>
In the FIFO cases of ll_atomic_open() and ll_lookup_nd() remove
spurious calls to ptlrpc_req_finished(). Explain that these cases are
unreachable in practice anyway.
