When running the test with -DASCII_TRACE it does not seem to crash the machine.
Looking through the code the following idom is seen in much of the code:
probe addevent.nfs.fop.llseek.return
+= _addevent.nfs.fop.llseek.return
{
update_record()
}
probe _addevent.nfs.fop.llseek.return
= nfs.fop.llseek.return
{
log_nfs_return(HOOKID_NFS_FOP_LLSEEK_RETURN,$return)
}
When -DASCII_TRACE is used on the command line, the update_record() becomes an
empty function and the order of the probes at a point becomes unimportant. It
seems like it would make sense to merge those probes together to make sure that
the operations are performed in the correct order.
