[PATCH v10 0/5] ring-buffer: Making persistent ring buffers robust

[Masami Hiramatsu (Google)]

Hi,

Here is the 10th version of improvement patches for making persistent
ring buffers robust to failures.
The previous version is here:

https://lore.kernel.org/all/177319273059.130641.10882692460536780093.stgit@xxxxxxxxxxxxxxxxxxxxxxxxxxxx/

In this version, I added a new patch to skip invalid page in rewinding
process[4/5], add entry_bytes check in the test [5/5] and do not
compile test code when CONFIG_RING_BUFFER_PERSISTENT_SELFTEST=n[5/5].

Thank you,

---
