Subject: [PATCH 0/2] Fix return code and improve feature check for synthetic uevents
Date: Wed, 5 Dec 2018 12:27:43 +0100 [thread overview]
Message-ID: <20181205112745.12276-1-prajnoha@redhat.com> (raw)
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.
