Subject: [PATCH] [CRYPTO]: Only reschedule if !in_atomic()
The netlink gfp_any() problem made me double-check the uses of in_softirq()
in crypto/*. It seems to me that we should be checking in_atomic() instead
of in_softirq() in crypto_yield. Otherwise people calling the crypto ops
with spin locks held or preemption disabled will get burnt, right?
