From mboxrd@z Thu Jan 1 00:00:00 1970 From: ira.weiny@intel.com Date: Fri, 9 Oct 2020 12:50:12 -0700 Subject: [Intel-wired-lan] [PATCH RFC PKS/PMEM 37/58] fs/ext2: Utilize new kmap_thread() In-Reply-To: <20201009195033.3208459-1-ira.weiny@intel.com> References: <20201009195033.3208459-1-ira.weiny@intel.com> Message-ID: <20201009195033.3208459-38-ira.weiny@intel.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: intel-wired-lan@osuosl.org List-ID: From: Ira Weiny These kmap() calls are localized to a single thread. To avoid the over head of global PKRS update use the new kmap_thread() call instead.
