[RFC v4 0/2] xfs: automatic relogging experiment

[Brian Foster <bfoster@redhat.com>]

Hi all,

Here's a v4 RFC for automatic relogging and probably the closest one IMO
to a non-RFC worthy implementation. There's still a few kinks, but this
might be the right combination of simplicity, effectiveness and
flexibility for future enhancement. Patch 1 adds the mechanism and patch
2 uses it for the quotaoff start intent. See the commit logs for further
details. 

Thoughts, reviews, flames appreciated.

- AIL based approach.

- CIL based approach.
rfcv2: https://lore.kernel.org/linux-xfs/20191122181927.32870-1-bfoster@redhat.com/
- Different approach based on workqueue and transaction rolling.
