Subject: Re: [PATCH 9/9] ext3: do not throttle metadata and journal IO
Date: Thu, 23 Apr 2009 08:27:16 -0400 [thread overview]
Message-ID: <20090423122716.GD2723@mit.edu> (raw)

P.S. I'm not saying that all of these problems need to be solved in a
single subsystem, or even in a single patch series. Just that someone
is thinking about how these ideas all fit together in a high-level
plan, which is written down. It could be wrong, but it really seems
to me that each time says, "so what about X", another piece gets
bolted on, as opposed to thinking about what the whole thing will look
like from the very beginning.
