Subject: Re: [PATCH v6 00/45] use refcount+RCU method to implement lockless
 slab shrink

Hi there,

Given that this series removes the old shrinker APIs and re-adds new
shrinker APIs with `EXPORT_SYMBOL_GPL`, is the intention to prevent any
out of tree module user which is incompatible with GPL to use the
shrinker APIs to register callbacks?

Or is there an alternative I was not able to find out by reading this
series?

Thank you for your work,
Kind regards,
