--- Comment #18 from Alan Somers <asomers@FreeBSD.org> ---
(In reply to Konstantin Belousov from comment #17)
I've tried it both ways.  Whether or not copy_file_range is enabled, if
nomsyncafterwrite is not set, then there is no crash.

And nomsyncafterwrite refers to msync immediately after mapped write.
