Subject: [PATCH 0/3] tracing: block-able ring_buffer consumer
Date: Thu, 27 Aug 2009 11:01:48 +0800 [thread overview]
Message-ID: <4A95F71C.1060607@cn.fujitsu.com> (raw)
The first patch fixes a bug of splice_read for ring_buffer, and makes
rb_get_reader_page() can be easily used by block-able/poll-able codes.
The other patches make consumer block-able and poll-able.
