[lustre-devel] [PATCH 19/27] lnet: libcfs: allow comma-separated masks

[James Simmons <jsimmons@infradead.org>]

From: Andreas Dilger <adilger@whamcloud.com>

For debug and changelog mask names, allow a comma-separated list
of names to be given, so that the space-separated list does not
need to be quoted for use.

Fix a couple of test cases where the debug parameter is set and
printed overly verbosely during tests.
