Hi,

Here is the 11th version of improvement patches for making persistent
ring buffers robust to failures.
The previous version is here:

https://lore.kernel.org/linux-trace-kernel/177374017536.2358053.12341235939816794384.stgit@mhiramat.tok.corp.google.com/

In this version, I updated [2/5] to do nothing by default since
flush_cache_vmap() does nothing on x86 but it can cause deadlock on
some architectures via on_each_cpu(), because other CPUs will be
stoppped when panic notifier is called.
Also update typo in [3/5], and fix to reset timestamp when invalid
whole ring buffer and skip pages which has invalid "timestamp"
instead of invalidating all ring buffers.

Thank you,

---
