Subject: [CRYPTO] api: Feed flag directly to crypto_yield
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8f21cf0d2bae04ece761595036c9da8328b279aa;p=linux-beck.git

[CRYPTO] api: Feed flag directly to crypto_yield

The sleeping flag used to determine whether crypto_yield can actually
yield is really a per-operation flag rather than a per-tfm flag.  This
patch changes crypto_yield to take a flag directly so that we can start
using a per-operation flag instead the tfm flag.
