New Revision: 276855
URL: https://svnweb.freebsd.org/changeset/base/276855
Log:
Change the default method for device_quiesce() to return 0 instead of
EOPNOTSUPP. The current behavior can mask real quiesce errors since
devclass_quiesce_driver() stops iterating over drivers as soon as it
gets an error (incluiding EOPNOTSUPP), but the caller it returns the
error to explicitly ignores EOPNOTSUPP.
