Subject: [PATCH 07/17] lustre/mdc: fix bad ERR_PTR usage in mdc_locks.c
Date: Fri, 28 Feb 2014 21:16:36 -0500 [thread overview]
Message-ID: <1393640206-20286-8-git-send-email-green@linuxhacker.ru> (raw)
In-Reply-To: <1393640206-20286-1-git-send-email-green@linuxhacker.ru>
From: "John L. Hammond" <john.hammond@intel.com>
In mdc_intent_open_pack() return an ERR_PTR() rather than NULL when
ldlm_prep_enqueue_req() fails. In mdc_intent_getattr_async() check the
return value of mdc_intent_getattr_pack() using IS_ERR(). Clean up the
includes in mdc_locks.c.
