From: Felix Fietkau Date: Mon, 9 Jan 2017 13:00:24 +0000 (+0100) Subject: kernel: remove ubifs xz decompression support X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=018d80007e6d9469077d938872e605f826010767;p=openwrt%2Fstaging%2Fjow.git kernel: remove ubifs xz decompression support It has been unused, and less useful than squashfs for cases where flash space usage matters.
