Re: [PATCH 3/4] x86/resctrl: Fix a deadlock due to inaccurate active reference of kernfs node

Hi Sasha,

The backporting for v4.14.x stable tree needs some manual tweaking due to
difference code bases:
1. x86/resctrl rename/re-arrange in v5.0 upstream kernel.
2. Code change in upstream commit cfd0f34e4cd5 ("x86/intel_rdt: Add
diagnostics when making directories").

The backporting for v4.19.x stable tree needs some manual tweaking due to
difference code bases: x86/resctrl rename/re-arrange in v5.0 upstream
kernel.

I will work on the backporting once this patch is merged into upstream.

Thank you.

NOTE: The patch will not be queued to stable trees until it is upstream.

How should we proceed with this patch?
