This is a note to let you know that I've just added the patch titled
kobj_uevent: Ignore if some listeners cannot handle message
to my driver-core git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core-2.6.git
in the driver-core-next branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will be merged to Linus's tree in the next big merge window after
the next kernel is released.
If you have any questions about this process, please let me know.

Subject: kobj_uevent: Ignore if some listeners cannot handle message
kobject_uevent() uses a multicast socket and should ignore
if one of listeners cannot handle messages or nobody is
listening at all.
Easily reproducible when a process in system is cloned
with CLONE_NEWNET flag.
