I didn't do any testing regarding changing the timeout used by the
wait_for_uevents function, either.
Nor did I. But I haven't seen the bugs since the loop went in either.
I need to rebuild with all modules and see if I can trip it up with USB
storage.
But udevtrigger is pretty much a drop-in replacement for walk_sysfs.
It appears so. walk_sysfs and wait_for_uevets functions removed.
Please see the attached replacement script. Can you replace and report
back please? Will put up a new tarball after I test with a modular
kernel.
TIA
