Subject: [PATCH] xfs_db: fix inverted logic in error path
Date: Tue, 11 Apr 2023 10:46:44 -0700 [thread overview]
Message-ID: <20230411174644.GI360889@frogsfrogsfrogs> (raw)
From: Darrick J. Wong <djwong@kernel.org>

This is backwards, so correct that.
check.c:3455 process_leaf_node_dir_v2_int() warn: variable dereferenced before check 'leaf'
