From aa23317d0268b309bb3f0801ddd0d61813ff5afb Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 25 Feb 2024 23:58:42 -0500 Subject: qibfs: fix dentry leak 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().
