Subject: x86: pageattr-test: remove srandom32 call
X-Git-Tag: v3.10-rc1~178^2~16
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4a7b4d2360175f67ab2c58effeeb8362a3057c25;p=karo-tx-linux.git

x86: pageattr-test: remove srandom32 call

pageattr-test calls srandom32() once every test iteration.  But calling
srandom32() after late_initcalls is not meaningfull.  Because the random
states for random32() is mixed by good random numbers in late_initcall
prandom_reseed().

So this removes the call to srandom32().
