Subject[PATCH AUTOSEL 5.1 086/219] crypto: testmgr - add some more preemption points
Date
From: Eric Biggers <ebiggers@google.com>

[ Upstream commit e63e1b0dd0003dc31f73d875907432be3a2abe5d ]

Call cond_resched() after each fuzz test iteration. This avoids stall
warnings if fuzz_iterations is set very high for testing purposes.

While we're at it, also call cond_resched() after finishing testing each
test vector.
