From 0e47b25cafb29338722f68e8c5a260aaf18ce92c Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 16 Dec 2022 15:15:52 -0500 Subject: [PATCH] btrfs: fix uninitialized variable warning in btrfs_cleanup_ordered_extents We can conditionally pass in a locked page, and then we'll use that page range to skip marking errors as that will happen in another layer. However this causes the compiler to complain because it doesn't understand we only use these values when we have the page. Make the compiler stop complaining by setting these values to 0.
