Revision d92b83f592d810aded2e5f90db5f560cc8cf577b authored by Kent Overstreet on 15 January 2024, 19:15:26 UTC, committed by Kent Overstreet on 21 January 2024, 18:27:09 UTC 
bcachefs: bch2_kthread_io_clock_wait() no longer sleeps until full amount
 
Drop t he loop in bch2_kthread_io_clock_wait(): this allows the code
that uses it to be woken up for other reasons, and fixes a bug where
rebalance wouldn't wake up when a scan was requested.

This raises the possibility of spurious wakeups, but callers should
always be able to handle that reasonably well.
