From 5f14b9246e8944243c70253b28830de619800d31 Mon Sep 17 00:00:00 2001 From: "Liam R. Howlett" Date: Tue, 6 Sep 2022 19:48:56 +0000 Subject: fs/proc/base: use the vma iterators in place of linked list Use the vma iterator instead of a for loop across the linked list. The link list of vmas will be removed in this patch set. Link: https://lkml.kernel.org/r/20220906194824.2110408-43-Liam.Howlett@oracle.com Signed-off-by: Liam R.
