Subject: [PATCH 0/2] ftrace: [BUGFIX] type of ring_buffer_oldest_event_ts() and showing of stats per cpu directory
Date: Tue, 09 Oct 2012 11:08:38 +0900 [thread overview]
Message-ID: <20121009020838.12110.90016.stgit@localhost.localdomain> (raw)
In-Reply-To: <1349148680-9509-1-git-send-email-dhsharp@google.com>
The following patch set fixes two bugs for ftrace.
[1/2]
This patch fixes type mismatch of ring_buffer_oldest_event_ts().
[2/2]
This fixes showing of stats per cpu directory for ftrace using counter or tsc
as a time stamp. This patch depends on David's patch series
(https://lkml.org/lkml/2012/10/1/652), but this bug already exists in the
counter mode.
Thank you,
