Subject: [PATCH-v2 6/9] pnfsblock: clean up _add_entry
Date: Thu, 12 Jan 2012 23:18:45 +0800	[thread overview]
Message-ID: <1326381528-2232-7-git-send-email-bergwolf@gmail.com> (raw)
In-Reply-To: <1326381528-2232-1-git-send-email-bergwolf@gmail.com>

It is wrong to kmalloc in _add_entry() as it is inside
spinlock. memory should be already allocated _add_entry() is called.
