From 5f07b6f367ff10ecc029e0b9e41b9fc5eac6968e Mon Sep 17 00:00:00 2001 From: Maxim Storchak Date: Thu, 9 Jan 2020 20:27:44 +0200 Subject: [PATCH] zram-swap: support swap priority If zram-backed swap is added after an existing swap, it gets a lower priority. Assiming that usually all other swaps are slower, there should be a way to assign a higher priority to zram swap.
