Subject: [PATCH] landlock: opened file never has a negative dentry
Date: Sun, 15 Jun 2025 01:30:11 +0100 [thread overview]
Message-ID: <20250615003011.GD1880847@ZenIV> (raw)
[don't really care which tree that goes through; right now it's
in viro/vfs.git #work.misc, but if somebody prefers to grab it
through a different tree, just say so]
