I'm not a dev Petre but just another XFS user. This is the best
"solution" I could come up with for your issue. I assumed this
"unnecessary" regularly scheduled activity was a house cleaning measure
and done intentionally; didn't dawn on me that it may be a bug.
Sorry I wasn't able to fully address your issue. If/until there is a
permanent fix for this you may want to bump this to 720000 anyway as an
interim measure, if you haven't already, as it should yield a
significantly better situation than what you have now. You'll at least
get something like ~1400 minutes of sleep per day instead of none,
decreasing your load/unload cycles from ~2880/day to ~120/day, if my
math is correct.
