kernel/throne_tracker: we just uninstalled the manager, stop looking for it by backslashxx · Pull Request #2584 · tiann/KernelSU

When the manager UID disappears from packages.list, we correctly
invalidate it — good. But, in the very next breath, we start scanning
/data/app hoping to find it again?

This event is just unnecessary I/O, exactly when we should be doing less.
Apparently this causes hangups and stuckups which is REALLY noticeable
on Ultra-Legacy devices.

Skip the scan — we’ll catch the reinstall next time packages.list updates.

Thanks. We even had to put this on a kthread man. (Linux 3.4 / 3.10)
