[PATCH v11 0/4] ring-buffer: Making persistent ring buffers robust

[Masami Hiramatsu (Google)]

Hi,

Here is the 12th version of improvement patches for making persistent
ring buffers robust to failures.
The previous version is here:

https://lore.kernel.org/all/177391152793.193994.8986943289250629418.stgit@xxxxxxxxxxxxxxxxxxxxxxxxxxxx/


In this version, I rebased it on tracing/fixes branch (thus
the first fix patch has been removed) and fixed
a build error which came from a copy-paste mistake.

Thank you,
