Subject: [PATCH v2] xen: Convert kmap() to kmap_local_page()
Date: Wed, 20 Apr 2022 01:43:28 +0200 [thread overview]
Message-ID: <20220419234328.10346-1-eng.alaamohamedsoliman.am@gmail.com> (raw)
kmap() is being deprecated and these usages are all local to the thread
so there is no reason kmap_local_page() can't be used.
Replace kmap() calls with kmap_local_page().
