-Subject: [PATCH] rngd_jitter: always read from entropy pipe before setting
- O_NONBLOCK
-
-Even with AES disabled, we want to make sure that jent_read_entropy() has
-already generated some entropy before we consider the the source
-initialized. Otherwise "Entropy Generation is slow" log spam will be
-emitteded until this has happened, which can take several seconds.
