Comes from Linux: a ton... Kconfig, Linker Script, MTD, UBI, UBIFS,
        ext2/3/4, jffs2, libfdt, many drivers, network stack,
        reiserfs, just to name a few.

Regularly synced: None.  Usually this only happens in irregular
	intervals, if incompatibilities or bugs (that have been
	fixed in more recent code) show up

Who: usually the responsible custodians

How: ideally thius should be a straightforward, though largely
	manual process.

Best regards,

Wolfgang Denk
