Subject: [PATCH next v2 0/6] exit: Put an upper limit on how often we can oops
Date: Wed,  9 Nov 2022 12:00:43 -0800	[thread overview]
Message-ID: <20221109194404.gonna.558-kees@kernel.org> (raw)

Hi,

This builds on Jann's v1 patch[1]. Changes in v2:
- move sysctl into kernel/exit.c (where it belongs)
- expand Documentation slightly

New stuff in v2:
- expose oops_count to sysfs
- consolidate panic_on_warn usage
- introduce warn_limit
- expose warn_count to sysfs

Jann Horn (1):
  exit: Put an upper limit on how often we can oops

  exit: Expose "oops_count" to sysfs
  panic: Consolidate open-coded panic_on_warn checks
  panic: Introduce warn_limit
  panic: Expose "warn_count" to sysfs
