If I implement a patch taking an unused flag and implementing IFF_SILENT,
in order to fix incorrect bonding active-backup behavior, will it get
accepted ?
If not, what can I do ?

Well, if we wanted just to cheat those checking tools, it is nice.

On wich card? I've been told that IPS4010 for example

Stephen,
Heres another on top of the others i sent. If you get the time, can
update your git tree with these patches?
If you are planning to make a release soon, please ping me - I have at
least one more patch that i need to work on.
cheers,
jamal
Update mirred usage to fix a bug noticed by
And
Add a dev_alloc_skb variant that takes a struct net_device * paramater.
For now that paramater is unused, but I'll use it to allocate the skb
from node-local memory in a follow-up patch. Also there have been some
other plans mentioned on the list that can use it.

Kevent subsystem incorporates several AIO/kqueue design notes and ideas.
Kevent can be used both for edge and level notifications. It supports
socket notifications (accept, send, recv), network AIO (aio_send(),
aio_recv() and aio_sendfile()), inode notifications (create/remove),
generic poll()/se
This patchset includes socket notifications and network asynchronous IO.
Network AIO is based on kevent and works as usual kevent storage on top
of inode.
When new socket is created it is associated with inode (to save some space,
since inode already has kevent_storage embedded) and when some act
This patch includes generic poll/select and timer notifications.
kevent_poll works simialr to epoll and has the same issues (callback
is invoked not from internal state machine of the caller, but through
process awake).
Timer notifications can be used for fine grained per-process time
managemen
This patch includes asynchronous propagation of file's data into VFS
cache and aio_sendfile() implementation.
Network aio_sendfile() works lazily - it asynchronously populates pages
into the VFS cache (which can be used for various tricks with adaptive
readahead) and then uses usual ->sendfile() c
