- Does not persist alloc info for stripes yet
 - Also does not yet include filesystem block/sector counts yet, from

0519b72dd2 bcachefs: Add a workqueue for journal reclaim
journal reclaim writes btree nodes, which can end up waiting for in
flight btree writes to complete, and btree write completions run out of
workqueues - so we can't run out of the same workqueue or we risk
deadlock

26609b619f bcachefs: Make bkey types globally unique
this lets us get rid of a lot of extra switch statements - in a lot of
places we dispatch on the btree node type, and then the key type, so
this is a nice cleanup across a lot of code.

Also improve the on disk format versioning stuff.

a420eea689 bcachefs: Set the last mount time using the realtime clock
This way the last mount time is actually meaningful instead of just being
various times from 1970 (which happens with the monotonic clock).

Also, roundup_pow_of_two() is undefined when passed in 0, so check before
calling it.

6eac2c2e24 bcachefs: Change how replicated data is accounted
Due to compression, the different replicas of a replicated extent don't
necessarily have to take up the same amount of space - so replicated
data sector counts shouldn't be stored divided by the number of
replicas.
