From 0a4dd35c67b144d8ef9432120105f1aab9293ee9 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Thu, 31 May 2012 16:26:46 -0700 Subject: kconfig: update compression algorithm info There have been new compression algorithms added without updating nearby relevant descriptive text that refers to (a) the number of compression algorithms and (b) the most recent one. Fix these inconsistencies. Signed-off-by: Randy Dunlap Reported-by: Cc: Lasse Collin Cc: "H.
