[PATCH] expose sysfs functions for sharing it This patch exposes the wait_for_sysfs functions to all possible users, so we need to maintain only one list of exceptions. The last list is hereby removed from udev.c.

[PATCH] don't wait for sysfs if the kernel(2.6.10-rc2) tells us what not to expect Newer kernels will tell us if we should wait for the "device" or the "bus" link. So don't waste the time with our lists or wait for the timeout.
