Date: Fri, 15 May 2020 11:44:28 -0700	[thread overview]
Message-ID: <20200515184434.8470-1-keescook@chromium.org> (raw)

Hello!

I wanted to get the pstore tree nailed down, so here's the v4 of
Pavel's series, tweaked for the feedback during v3 review.

-Kees

v4:
- rebase on pstore tree
- collapse shutdown types into a single dump reason
  https://lore.kernel.org/lkml/CA+CK2bAPv5u1ih5y9t5FUnTyximtFCtDYXJCpuyjOyHNOkRdqw@mail.gmail.com/
- fix dump_oops vs max_reason module params
  https://lore.kernel.org/lkml/20200512233504.GA118720@sequoia/
- typos
  https://lore.kernel.org/lkml/4cdeaa2af2fe0d6cc2ca8ce3a37608340799df8a.camel@perches.com/
- rename DT parsing routines ..._size -> ..._u32
  https://lore.kernel.org/lkml/CA+CK2bCu8eFomiU+NeBjVn-o2dbuECxwRfssNjB3ys3caCbXeA@mail.gmail.com/
v3: https://lore.kernel.org/lkml/20200506211523.15077-1-keescook@chromium.org/
v2: https://lore.kernel.org/lkml/20200505154510.93506-1-pasha.tatashin@soleen.com
v1: https://lore.kernel.org/lkml/20200502143555.543636-1-pasha.tatashin@soleen.com

Kees Cook (3):
  printk: Collapse shutdown types into a single dump reason
  printk: Introduce kmsg_dump_reason_str()
  pstore/ram: Introduce max_reason and convert dump_oops

Pavel Tatashin (3):
  printk: honor the max_reason field in kmsg_dumper
  pstore/platform: Pass max_reason to kmesg dump
  ramoops: Add max_reason optional field to ramoops DT node
