Hi,
I am running a kernel about a week old (HEAD) and some world from
around 22 Sep. For some reason I had not installed world yet (though
built).
Now I am seeing this:
bz@host:~> touch abc
bz@host:~> ls -l abc
-rw-rw-r-- 1 bz staff 0 Jan 23 08:51 abc
bz@host:~> cp abc abd
cp: abc: Invalid argument
This works fine with a some day old HEAD and 5.2R so I first suspected
that it may be related to the statfs changes and my inconstistent
userspace/kernel. COMPAT_FREEBSD4 is set in the new kernel of course.
Then I did a ktrace cp abc abd. Here is the output of the relevant
parts of kdump output:

If I remember correctly there had been some changes around this...
Compat problem with new kernel and old binaries ?
Just wanted to let you know.
Building HEAD and kernel now, creating a backup and going to
install then.
