Planning spares for FreeBSD-9

To keep KPI/KBI stability for FreeBSD-9 please add spares you will need to this page.

Please always add your login and a description of the proposed changes under the subsystem section, so someone can get back to you in case of questions.

In case you feel eligible for a subsystem please add your name to the heading stating you will poll people and do the commit adding the spares until Saturday July 16th.

Spares are getting committed. You are too late. If you still need spares you may contact Release Engineering.

• bz – per socket timer support, a mix of what is supported by Linux, NetBSD, Apple and used by various projects like openldap and cyrus-imap.
• luigi - pointer to netmap-specific data for interface that will support it. See http://info.iet.unipi.it/~luigi/netmap/ for more info.
• cnicutar – TCP User Timeout Option
• xxx - route caching.

• pjd – support for direct I/O and support for provider's property changes (like mediasize changes)
