Subject: [PATCH 0/2] Fix return code and improve feature check for synthetic uevents

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.

Peter Rajnoha (2):
  kobject: return error code if writing /sys/.../uevent fails
  kobject: add kernel/uevent_features sysfs file
