--- Comment #4 from Alan Somers <asomers@FreeBSD.org> ---
I'll try that patch shortly.  In the meantime, I've discovered a much quicker
way to reproduce the problem by increasing the operation sizes.  Change the
copy_file_range.toml file to contain this:

flen = 524288
nomsyncafterwrite = true
[opsize]
max = 131072
min = 65536
[weights]
truncate = 1
fsync = 1
fdatasync = 1
punch_hole = 0
sendfile = 1
write = 10
read = 10
copy_file_range = 10
