Subject: [PATCH v4 0/2] tracing: Make persistent ring buffer freeable

Hi,

Here is the 4th version of patches for making the persistent ring buffer
freeable. The previous version is here;

https://lore.kernel.org/all/173928521419.906035.17750338150436695675.stgit@devnote2/

In this version, I used free_reserved_area() instead of custom releasing
code. This seems working correctly. Thanks Mike!


Thank you,
