From 565dfeb1280343fb3f838581169e5d7a1c947862 Mon Sep 17 00:00:00 2001 From: Rui Salvaterra Date: Thu, 1 Apr 2021 14:36:33 +0100 Subject: [PATCH] zram-swap: bail out early if the kernel doesn't support swap Since KERNEL_SWAP is only enabled by default for !SMALL_FLASH targets, we need to check if the current kernel supports swap before trying to configure zram-swap, as opkg can't check for kernel dependencies.
