LSF 2013 call for participation?

LSF 2013 call for participation?

[Jan Kara]

  Hi,

  I wanted to ask about this year's LSFMM summit - I didn't see any call
for participation yet although previous years it was sent out before
Christmas. What's going on? I believe things should get moving soon so that
invited people can arrange for visa / plane tickets...

PS: If my memory serves well (thanks goes to Mel for reminding me), Martin
was appointed this year's chief organizer.

Really? I always thought they went out in January. In any case we are
getting the call rolling.

And for those that want to plan ahead the dates are April 18th and 19th
in San Francisco. This year we're trailing the Collab Summit instead of
preceding it:

  Thanks! Looking forward to it.

There are a few things I'd like to hold a discussion about...

 - How do we get from bcache/flashcache/dm-cache/enhanceio to a single upstream
   driver?  If we merge one of them, then can we cherry-pick the more easily
   pluggable pieces of each into whatever gets merged?  Which one would we
   merge as a basis for the others?

 - Stable pages part 3: Modifying existing block devices.  A number of block
   devices and filesystems provide their own page snapshotting, or play tricks
   with the page bits to satisfy their own stability requirements.  Can we
   eliminate this?

Also, miscellaneous other odd topics:

 - How many of the infrequently-tested mount options in ext4/others can we get
   away with eliminating?  Or at least hiding them behind a "pleaseeatmydata"
   mount flag to minimize (hopefully) the amount of accidental data loss due to
   wild mount incantations?

 - Update on exposing T10/DIF data to userspace via the preadv/pwritev aio
   interface.  I ought to publish some code first.

 - A discussion of deduplication could be fun, though I'm not sure its memory
   and processing requirements make it a great candidate for kernel code, or
   even general usage.  I'm not even sure there's a practical way to, say, have
   a userspace dedupe tool that could listen for delayed allocations and try to
   suggest adjustments before commit time.

  I guess this is more about sending patches than agreeing on how to do
it. But you can give a quick status update so that respective maintainers
know about the current situation.

  I'm interested in this discussion as well. But be aware that this
question is coming up for at least last two years if I remember right. And
again if you come up with suggestions for particular options, we can speak
about it. Actually I have a plan to prepare some concrete suggestions for
ext4 workshop / LSF. So just tell me if you plan to work on this so that we
don't duplicate the effort.

  I think userspace is a better place for efficient deduplication... Plus
you have to implement COW to handle when deduplicated block is written.
