The branch stable/13 has been updated by asomers: URL: https://cgit.FreeBSD.org/src/commit/?id=2c999421c44b3f8b30b3c2057284f79c7a193f15 commit 2c999421c44b3f8b30b3c2057284f79c7a193f15 Author: Alan Somers <asomers@FreeBSD.org> AuthorDate: 2022-04-29 13:59:29 +0000 Commit: Alan Somers <asomers@FreeBSD.org> CommitDate: 2022-05-23 19:11:08 +0000 fusefs: add a test for the subtype= option At mount time server can set, for example, "subtype=xfs", so that mount(8) will later show the mountpoint's file system as "fusefs.xfs". fusefs has had this feature ever since the original GSoC commit in 2012, but there's never been a test for it.
