From 31d270fd98d196578223e5b568a0bd3bc6028b09 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Thu, 25 Feb 2021 17:16:03 -0800 Subject: mm: add an 'end' parameter to pagevec_lookup_entries Simplifies the callers and uses the existing functionality in find_get_entries(). We can also drop the final argument of truncate_exceptional_pvec_entries() and simplify the logic in that function.
