[OpenWrt-Devel] [PATCH v2] zram-swap: set a high priority for the swap

[Juan Orti Alcaine]

The zram swap must be activated with a higher priority than
disk-based swap, so it is used before any other.
This patch activates the zram-based swap with a priority of 100.

---
v2:
  Fallback to no priority when swapon doesn't support it.
