Subject: [PATCH v2] drivers/vmw_vmci: Show correct get_user_pages_fast upon failure
Date: Tue, 17 Feb 2015 14:29:21 -0800 [thread overview]
Message-ID: <1424212161.2046.108.camel@stgolabs.net> (raw)
In-Reply-To: <20150217222045.GB27762@kroah.com>
As of 240ddd495a9 (vmw_vmci: Convert driver to use get_user_pages_fast())
we no longer user get_user_pages(), thus update the warning.
Also convert to pr_debug, which is a more appropriate level of logging.
