-# Minimalist mconsole exec patch

-# 3.10 version (with bit more synchronous behavior) by fingon at iki dot fi
-# Adaptation to kernel 3.3.8 made by David Fernández (david at dit.upm.es) for
-# Starting point: mconsole-exec-2.6.30.patch for kernel 2.6.30
-# Author of original patch: Paolo Giarrusso, aka Blaisorblade
-# (http://www.user-mode-linux.org/~blaisorblade)
-#
-# Known misfeatures:
-#
-# - If output is too long, blocks (and breaks horribly)
-# (this misfeature from 3.10 patches, when minimalizing the patch;
-# workaround: redirect to a shared filesystem if long output is expected)
-#
-# - Nothing useful is done with stdin

-Subject: [PATCH v1 2/2] um: increase default virtual physical memory to 64 MiB
-To: linux-um at lists.infradead.org
-Cc: Richard Weinberger <richard at nod.at>,
- Anton Ivanov <anton.ivanov at cambridgegreys.com>,
- Johannes Berg <johannes at sipsolutions.net>
-
-The current 32 MiB of RAM causes OOMs to appear shortly after
-booting in a minimal OpenWrt 22.03 configuration with a
-5.10.134 kernel.
-
-Of course, passing a "mem=64M" (from the --help text) parameter
-works too, but it produces the following (info) message:
-
-| [ 0.000000] Unknown kernel command line parameters "mem=64M", will be passed to user space.
-
-That's why, I think it would be nicer, if this is working out
-of the box again :).
