Author: mav Date: Wed Jan 30 16:50:53 2019 New Revision: 343582 URL: https://svnweb.freebsd.org/changeset/base/343582 Log: Relax BIO_FLUSH ordering in da(4), respecting BIO_ORDERED. r212160 tightened this from always using MSG_SIMPLE_Q_TAG to always MSG_ORDERED_Q_TAG. Since it also marked all BIO_FLUSH requests with BIO_ORDERED, this commit changes nothing immediately, but it returns BIO_FLUSH callers ability to actually specify ordering they really need, alike to other request types.
