From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alaa Mohamed Date: Sat, 16 Apr 2022 03:19:20 +0200 Subject: [Intel-wired-lan] [PATCH v2] intel: igb: igb_ethtool.c: Convert kmap() to kmap_local_page() Message-ID: <20220416011920.5380-1-eng.alaamohamedsoliman.am@gmail.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: intel-wired-lan@osuosl.org List-ID: The use of kmap() is being deprecated in favor of kmap_local_page() where it is feasible. With kmap_local_page(), the mapping is per thread, CPU local and not globally visible.
