Subject: [PATCH 3/5] IB/hfi1: Adjust another size determination in hfi1_user_sdma_alloc_queues()
Date: Fri, 10 Feb 2017 22:03:23 +0100 [thread overview]
Message-ID: <0fdf4d81-58d7-c6fc-b37f-41d47675dd83@users.sourceforge.net> (raw)
In-Reply-To: <8a997282-09c7-0f9f-645e-d7c6e8c79e67@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 10 Feb 2017 08:50:45 +0100
* Pass a product for a call of the function "vmalloc_user" without storing
it in an intermediate variable.
* Delete the local variable "memsize" which became unnecessary with
this refactoring.
