Subject: [PATCH 5/5] ring-buffer: Remove unused macro RB_TIMESTAMPS_PER_PAGE
Date: Tue, 19 Oct 2010 13:54:37 -0400 [thread overview]
Message-ID: <20101019194204.680033652@goodmis.org> (raw)
In-Reply-To: 20101019175432.854431527@goodmis.org
[-- Attachment #1: 0005-ring-buffer-Remove-unused-macro-RB_TIMESTAMPS_PER_PA.patch --]
[-- Type: text/plain, Size: 883 bytes --]
From: Steven Rostedt <srostedt@redhat.com>
With the binding of time extends to events we no longer need to use
the macro RB_TIMESTAMPS_PER_PAGE. Remove it.
