Subject: [PATCH -rt 6/8] preempt_max_latency in all modes
Date: Tue, 28 Aug 2007 14:37:54 -0700	[thread overview]
Message-ID: <20070828213801.391940192@mvista.com> (raw)
In-Reply-To: 20070828213748.790253419@mvista.com

[-- Attachment #1: add-preempt-max-latency-for-all-timing-modes.patch --]
[-- Type: text/plain, Size: 761 bytes --]

This enables the /proc/preempt_max_latency facility for timing modes,
even if event tracing is disabled. Wakeup latency was the only one
that had this feature in the past.
