Subject: crypto: chainiv - Use kcrypto_wq instead of keventd_wq
X-Git-Tag: v2.6.30-rc1~677^2~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0a2e821d627ad5ced23cf31137625b81cc205e0f;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git

crypto: chainiv - Use kcrypto_wq instead of keventd_wq

keventd_wq has potential starvation problem, so use dedicated
kcrypto_wq instead.
