Subject: [patch 113/178] mm/vmalloc: remove unmap_kernel_range
Date: Thu, 29 Apr 2021 22:59:01 -0700	[thread overview]
Message-ID: <20210430055901.AnsCwhAJF%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210429225251.02b6386d21b69255b4f6c163@linux-foundation.org>

Subject: mm/vmalloc: remove unmap_kernel_range

This is a shim around vunmap_range, get rid of it.

Move the main API comment from the _noflush variant to the normal
variant, and make _noflush internal to mm/.
