[PATCH v6 0/3] ring-buffer: Making persistent ring buffers robust

[Masami Hiramatsu (Google)]

Hi,

Here is the 6th version of improvement patches for making persistent
ring buffers robust to failures.
The previous version is here:

https://lore.kernel.org/all/177211310553.419230.7846100548994399256.stgit@xxxxxxxxxxxxxxxxxxxxxxxxxxxx/

In this version, I introduced asm/ring_buffer.h file for wrapping
flush ring buffer function and use dcache_clean_pop() for arm64[1/3]
also, showing invalid page detection (first time for each cpu)
message when validating the persistent ring buffer[3/3]. 

Thank you,
