(In reply to John Millikin from comment #2)
Ok, I agree.  As the man page says, l_whence should be set to SEEK_SET on
return from a successful F_GETLK operation.  After all, it's describing some
other lock, not the one you queried about.  However, I don't see any reason why
l_whence should be set to SEEK_SET on return from F_SETLK or F_SETLKW.

(There's a separate problem with SEEK_END and F_SETLK, which I'll fix.  fusefs
doesn't correct the offset passed to the daemon.)
