But it saves time for the user, who does not have to run around chasing
links, carefully checking for a kernel match, downloading, patching,
building and installing a single purpose kernel, and bringing it up on
a machine that would probably have only required one click on the new
filesystem option otherwise. The considerable time thus saved can be
invested profitably in running test cases and filing bug reports.

True, but the trick here is getting started. It is much easier to
justify the effort of going out and getting the latest patch if one
knows from experience that it basically already works.

Are you sure about that? I see 33 messages on linux-ext4 yesterday,
from a broad range of contributors. Versus eight from a much narrower
range of contributors, Oct 4 a year ago.

There is little question that an early merge helps both developers and
users employ their time more efficiently, once a project is past the
point where we wonder about its value and/or viability. In my opinion,
Btrfs clearly has both. Particularly because we need a way to stem the
loss of mindshare to ZFS in the storage space, which is significant at
the moment. And Btrfs is closest to the finish line in that regard.
It needs all the help it can get.
