[PATCH v4 0/3] ring-buffer: Making persistent ring buffers robust

Posted by Masami Hiramatsu (Google) 1 month, 3 weeks ago

Hi,

Here is the 4th version of improvement patches for making persistent
ring buffers robust to failures.
The previous version is here:

https://lore.kernel.org/linux-trace-kernel/177186335195.133407.907308822749006594.stgit@devnote2/

In this version, I fixed to move rb_commit_index() after the
definition of ring_buffer_per_cpu[2/3].

Thank you,

---
