[PATCH v8 0/2] ring-buffer: Making persistent ring buffers robust

[Masami Hiramatsu (Google)]

Hi,

Here is the 8th version of improvement patches for making persistent
ring buffers robust to failures.
The previous version is here:

https://lore.kernel.org/all/177289358078.248514.14947007976699929481.stgit@devnote2/

In this version, I cleaned up and add comments, remove unused var,
and clear RB_MISSED_* flags when reading recovered subbufs.[1/2]

Thank you,
