Subject: [PATCH 0/2] psi: two division fixes
Date: Tue,  3 Dec 2019 13:35:22 -0500	[thread overview]
Message-ID: <20191203183524.41378-1-hannes@cmpxchg.org> (raw)

Hi Peter,

here is a patch that should fix the rare div0 crashes reported by
Jingfeng, and a second patch for a div32-with-64-bit-divisor issue
spotted during code review.

Can you please take a look and route them through the scheduler tree?

Thanks!
