Hi Jan,

Thank you for the review. 

You're right - I need to investigate further why these dentries survive until unmount if dput() should destroy DCACHE_DISCONNECTED dentries immediately. 
I'll add more detailed tracing to understand the actual reference counting and dentry state throughout the lifecycle. 
I may have misdiagnosed the root cause even though the fix addresses the symptom

Best Regards
