Subject: [patch 031/127] arch/kmap_atomic: consolidate duplicate code
Date: Thu, 04 Jun 2020 16:47:42 -0700 [thread overview]
Message-ID: <20200604234742.fDVdd5Bbs%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200604164523.e15f3177f4b69dcb4f2534a1@linux-foundation.org>
From: Ira Weiny <ira.weiny@intel.com>
Subject: arch/kmap_atomic: consolidate duplicate code
Every arch has the same code to ensure atomic operations and a check for
!HIGHMEM page.
Remove the duplicate code by defining a core kmap_atomic() which only
calls the arch specific kmap_atomic_high() when the page is high memory.
[akpm@linux-foundation.org: coding style fixes]
