Subject: [PATCH v2 8/8] ring-buffer: Remove unused macro RB_TIMESTAMPS_PER_PAGE
Date: Wed, 20 Oct 2010 21:39:14 -0400 [thread overview]
Message-ID: <20101021014144.618212499@goodmis.org> (raw)
In-Reply-To: 20101021013906.507064528@goodmis.org
[-- Attachment #1: 0008-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.
