Subject: [PATCH v4 0/2] Fix lockdep warning with nested instances of i2c-mux
Date: Fri, 20 Jul 2018 10:39:12 +0200	[thread overview]
Message-ID: <20180720083914.1950-1-peda@axentia.se> (raw)

Hi!

Ping. This is almost a resend of v3, but I added tested-by tags from
John and unwrapped a line in the commit message, so it's a v4.

How is this going to find its way to Linus? I can move this through
the i2c-mux tree, but I obviously need a tag for patch 1/2 for that...

Cheers,
Peter

Changes since v3    https://lkml.org/lkml/2018/5/24/994
- Added Tested-by tags from John.
- Unwrapped commit message for patch 2/2.

Changes since v2    https://lkml.org/lkml/2018/5/24/176
- EXPORT_SYMBOL_GPL(rt_mutex_lock_nested) is more appropriate (the
  rt_ prefix was missing).

Changes since v1    https://lkml.org/lkml/2018/5/24/93
- Further compile tests indicated a missing #define for rt_mutex_lock
  with lockdep enabled, so that one is added.
- I have verified that I don't get any lockdep splat for a local i2c-mux
  setup with these patches applied, and that I do without them.

Cheers,
Peter
