Author: asomers Date: Thu Jun 20 21:29:28 2019 New Revision: 349244 URL: https://svnweb.freebsd.org/changeset/base/349244 Log: fusefs: raise protocol level to 7.13 This protocol version adds one new feature: the ability for the server to set the maximum number of background requests and a "congestion threshold" with ill-defined properties. I don't know of any fuse file systems in ports that use this feature, so I'm not implementing it.
