Hi Oleg,
There are 45 tests in the fcntl section of the POSIX test suite. I
think around 10 of them require the the filesystem is mounted with
flock, so I don't know about "comprehensive", but there's a start.

Just wondering is anyone else hitting this:
1.4.8 (correctly I guess!) started rejecting locks unless the
"flock" mount option was used, as per changelog note for bug
#10743. I guess in the
past it faked success but the file wasn't really locked?
File was locked, but only on a that node, other nodes won't see it.
=> So, what's the latest on file lock support in general in lustre?
We are trying to fix when we learn about problems with it.
(see bug 11415 if you plan to use fcntl locks with anything above
2.6.5 kernel)
Actually using the "flock" mount option doesn't seem to be a
solution, as AFAIK it's known incomplete in 1.4.x (?): Unless flock
is supposed to be working fully in 1.4.8, in which case, well,
maybe there is a bug to be found...
Well, we found one already.
I wonder if there are any comprehensive flock/fcntl locking testsuites
we can try to use?
Bye,
Oleg
