How to transfer data from user-space to kernel module?

[Yue Chen]

I have text or binary files in user-space (file systems), how to transfer them to kernel modules?

For Linux, there are approaches like:

• reading files in kernel modules;
• virtual filesystems, e.g. /proc, /sys, configfs, relayfs, debugfs;
• netlink;
• poll() / epoll() & related.

For FreeBSD, how to do it efficiently and conveniently?
