[PATCH 0/5] btrfs: block group cleanups

[Josef Bacik <josef@toxicpanda.com>]

I'm reworking our relocation and delete unused block group workqueues which
require some cleanups of how we deal with flags on the block group.  We've had a
bit field for various flags on the block group for a while, but there's a subtle
gotcha with this bitfield in that you have to protect every modification with
bg->lock in order to not mess with the values, and there were a few places that
we weren't holding the lock.

Rework these to be normal flags, and then go behind this conversion and cleanup
some of the usage of the different flags.  Additionally there's a cleanup around
when to break out of the background workers.  Thanks,

Josef
