Large FITRIM runtime is not actually an AGF locking latency problem
anymore....

... because I fixed this problem in commit 89cfa899608f ("xfs:
reduce AGF hold times during fstrim operations").

That commit also fixed this problem.

It already does this.

Ah, so this is a completely different problem to what you describe
above. i.e. The problem with "sub-ag" fstrim is simply that finding
block range limited free extents is costly in terms of overall time
and CPU usage when you do it via the by-count btree instead of the
by-bno btree...

Ok, it's fine to do a by-bno search in this case...

... but It doesn't change the locking latency of fstrim at all.
Locks are still only held for batches of 100 free extent lookups...
I think a commit message update is necessary. :)

I'd prefer that we don't copy-n-paste-n-subtly-modify code like
this. There's very little different between the two gather cases -
the initial cursor setup and the loop exit criteria - so they should
be easy to use a common core loop.

I think this is the wrong place to do this. I agree that it is
sensible to use ag-constrained agbnos here, but we should do it
properly and not make the code unnecessarily difficult to maintain
by using unconstrained daddrs in one gather function and constrained
agbnos in another.
Here's a completely untested, uncompiled version of this by-bno
search I just wrote up to demonstrate that if we pass ag-confined
agbnos from the top level, we don't need to duplicate this gather
code at all or do trim range constraining inside the gather
functions...
