From 55b2598e84e97efc5d952958cb5e34236c43276b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 24 Sep 2020 08:51:32 +0200 Subject: bdi: initialize ->ra_pages and ->io_pages in bdi_init Set up a readahead size by default, as very few users have a good reason to change it. This means code, ecryptfs, and orangefs now set up the values while they were previously missing it, while ubifs, mtd and vboxsf manually set it to 0 to avoid readahead.
