Description Nikos Vassiliadis 2010-01-21 16:40:06 UTC
Creating and filling a big malloc-backed memory disk is a way to panic
the system. This could be easily avoided if the reseve option became the
default for malloc disks.

Fix: The attached patch adds reserve to the defaults for malloc disks

Patch attached with submission follows:
How-To-Repeat: mdconfig -at malloc -s 200m
dd if=/dev/zero of=/dev/md0
