Subject: [PATCH v2 1/1] genirq/cpuhotplug: Bump debugging information print down to KERN_DEBUG
Date: Mon, 16 Aug 2021 14:48:17 +0100	[thread overview]
Message-ID: <> (raw)

This sort of information is only generally useful when debugging.

No need to have these sprinkled through the kernel log otherwise.

Real world problem:

  During pre-release testing these have an affect on performance on
  real products.  To the point where so much logging builds up, that
  it sets off the watchdog(s) on some high profile consumer devices.
