[Xenomai] switchtest in Xenomai-3.0-rc2

[Jeff Webb <jeff.webb@nta-inc.net>]

In Xenomai-3.0-rc2, doc/asciidoc/TROUBLESHOOTING.COBALT.adoc still says this:


=== Issues when running the _switchtest_ program

==== pthread_create: Resource temporarily unavailable

The switchtest test creates many kernel threads, this means that the
options +CONFIG_XENO_OPT_SYS_HEAPSZ+ and
+CONFIG_XENO_OPT_SYS_STACKPOOLSZ+, in your kernel configuration,
should be configured to large enough values. Try increasing them,
rebuilding the kernel.


but, it looks like CONFIG_XENO_OPT_SYS_STACKPOOLSZ has been removed in Xenomai-3.  Is there another an equivalent variable that I might need to increase, or is increasing CONFIG_XENO_OPT_SYS_HEAPSZ sufficient to get rid of the error below?
