From 056785ea51a657f55953f6b0195baac2cceb1f16 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 12 Dec 2013 15:49:21 +0200 Subject: net/sunrpc/cache: simplify code by using hex_pack_byte() hex_pack_byte() is a fast way to convert a byte in its ASCII representation. We may use it instead of custom approach. Signed-off-by: Andy Shevchenko Signed-off-by: J.

As new commits only seem to use prandom_u32 there is no use to keep them around. This change makes it easier to grep for users of prandom_u32.
