From 02ee394a5d899d9bd2f0759382e9481cab6166f8 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 25 Feb 2024 23:58:42 -0500 Subject: qibfs: fix dentry leak [ Upstream commit aa23317d0268b309bb3f0801ddd0d61813ff5afb ] simple_recursive_removal() drops the pinning references to all positives in subtree. For the cases when its argument has been kept alive by the pinning alone that's exactly the right thing to do, but here the argument comes from dcache lookup, that needs to be balanced by explicit dput().
