[PATCH 1/4] random: use device attach events for entropy

2013-11-03 Thread Theodore Ts'o
Some investigation from FreeBSD shows that there is entropy available from measuring the device attach times: http://lists.randombit.net/pipermail/cryptography/2013-October/005689.html This will hopefully help us more quickly initialize the entropy pools while the system is booting (which is one
