From d241a95f3514a5eb544dfd8d9d141ffd1c89b707 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 26 Jun 2019 15:49:21 +0200 Subject: block: optionally mark pages dirty in bio_release_pages A lot of callers of bio_release_pages also want to mark the released pages as dirty. Add a mark_dirty parameter to avoid a second relatively expensive bio_for_each_segment_all loop.
