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.
