Two small patches to aid handling of synthetic uevents back in userspace:
- Return error code back to userspace on /sys/.../uevent file write
failure so userspace knows and it can act accordingly.
- Add new 'kernel/uevent_features' sysfs file to make it possible for
userspace to check that the extended synthetic uevent arguments are
supported without relying on kernel version check only.
