From 1ec49744ba83f0429c5c706708610f7821a7b6f4 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 16 Dec 2022 15:15:58 -0500 Subject: [PATCH] btrfs: turn on -Wmaybe-uninitialized We had a recent bug that would have been caught by a newer compiler with -Wmaybe-uninitialized and would have saved us a month of failing tests that I didn't have time to investigate.
