From 7644a46b611ca4a27e96c23b04bd4d457f72c8eb Mon Sep 17 00:00:00 2001 From: "Liam R. Howlett" Date: Thu, 8 Apr 2021 16:20:21 -0400 Subject: [PATCH] lib/test_hmm: Use vma_lookup() in dmirror_migrate() vma_lookup() will only return the vma which contains the address and will not return the next vma. This allows the code to easier to understand. Signed-off-by: Liam R.
