Hi,

Here is the 14th version of improvement patches for making persistent
ring buffers robust to failures.
The previous version is here:

https://lore.kernel.org/all/177440549083.1529621.15486836623498328967.stgit@mhiramat.tok.corp.google.com/

This version adds a patch to reset RB_MISSED_* flags when validating
persistent ring buffer [4/5] and renames selftest config to
CONFIG_RING_BUFFER_PERSISTENT_INJECT, clears meta->nr_invalid/entry_bytes
after testing and adds test commands in config comment.[5/5]

I heard the first 3 patches are already under tested, but it is
not pushed yet. So I left those in this version.

Thank you,

---
