From 44e9376a371ec8433cdf6ce683e42215d0ba0c38 Mon Sep 17 00:00:00 2001 From: Fabian Blaese Date: Sat, 28 Mar 2020 17:09:58 +0100 Subject: [PATCH] kernel: Reduce memory usage by reducing squashfs fragment cache size MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reducing the amount of squashfs fragments cached in memory might reduce memory usage, especially for systems with very little memory and big squashfs blocksizes. Because only ar71xx-tiny contains 32/4 (memory/flash) devices, the reduction of the fragment cache is only applied to the ar71xx bsp.
