Subject: [PATCH iproute2-next 0/2] Add copy-on-fork to get sys command
Date: Wed, 28 Apr 2021 14:42:29 +0300	[thread overview]
Message-ID: <20210428114231.96944-1-galpress@amazon.com> (raw)

This is the userspace part for the new copy-on-fork attribute added to
the get sys netlink command.

The new attribute indicates that the kernel copies DMA pages on fork,
hence fork support through madvise and MADV_DONTFORK is not needed.

Kernel series was merged:

Thanks
