I have an unused disk ( no mounted filesystems ) that I put to sleep (
hdparm -Y ) and every 10 minutes, the link is reset to process a
request coming from a short lived process named "pool". I think it is
a kernel work queue. I inserted a dump_stack() but it stops when it
gets to the syscall and so doesn't trace back into what work item is
running. How can I figure out what work item is doing this?
