From 26b433d0da062d6e19d75350c0171d3cf8ff560d Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 6 Sep 2017 16:21:15 -0700 Subject: fscache: remove unused ->now_uncached callback Patch series "Ranged pagevec lookup", v2. In this series I make pagevec_lookup() update the index (to be consistent with pagevec_lookup_tag() and also as a preparation for ranged lookups), provide ranged variant of pagevec_lookup() and use it in places where it makes sense. This not only removes some common code but is also a measurable performance win for some use cases (see patch 4/10) where radix tree is sparse and searching & grabing of a page after the end of the range has measurable overhead. This patch (of 10): The callback doesn't ever get called. Remove it.
