We're in the process of turning bset.c into library code, so none of the code in
that file should know about struct cache_set or struct btree - so, move the
btree traversal part of the stats code to sysfs.c.

Soon, bset.c won't need to depend on struct btree.

More disentangling bset.c from the rest of the bcache code - soon, the
sorting routines won't have any dependencies on any outside structs.

bcache: Rework allocator reserves2014-01-08T21:05:09ZKent Overstreet2013-12-17T09:29:34Zurn:sha1:78365411b344df35a198b119133e6515c2dcfb9f
We need a reserve for allocating buckets for new btree nodes - and now that
we've got multiple btrees, it really needs to be per btree.
This reworks the reserves so we've got separate freelists for each reserve
instead of watermarks, which seems to make things a bit cleaner, and it adds
some code so that btree_split() can make sure the reserve is available before it
starts.

bcache: New writeback PD controller2013-12-16T22:22:59ZKent Overstreet2013-11-11T21:58:34Zurn:sha1:16749c23c00c686ed168471963e3ddb0f3fcd855
The old writeback PD controller could get into states where it had throttled all
the way down and take way too long to recover - it was too complicated to really
understand what it was doing.
This rewrites a good chunk of it to hopefully be simpler and make more sense,
and it also pays more attention to units which should make the behaviour a bit
easier to understand.

More testing ftw! Also, now verify mode doesn't break if you read dirty
data.

It never really made sense to expose this, so just kill it.
