| I've added some others for mainline:
| 
| pushing into 2.5:
| 
| * IPv6:
|   - most core IPv6 ND, autoconf, bugfixes, etc. have gone in,
|     including privacy extensions.  Some in 2.4.20, more in 2.4.21.
|   - IPSec accepted by Dave Miller todayish, pushing to Linus
|     probably 2.5.65
|   - MIPv6 pending; may or may not make it?  MN & CN probably will, HA
|     may not
|   - SNMP (Randy/Yixiong) should make 2.5, but worried about changes to
|     /proc
| * POSIX
|   - timers (POSIX interface to clocks & timers is in)
|   - possible bugs (see below)
| * IPMI
| 
| waiting for 2.7:
| 
| * IPv6:
|   - maybe MIP, esp. HA
| *  POSIX:
|   - hi-res timers
| * TIPC
| 
| stalled:
| 
| * kernel debugger
| * kernel dumps
| 
| -----
| 
| Non-kernel, therefore not subject to this logic:
| 
| (These items may have kernel dependencies, but will not be shipped as
| part of the kernel.)
| 
| Well under way:
| 
| * OpenPOSIX test suite
| * Hot device identity (status?)
|   (MontaVista one may have had kernel change, Nokia was user-only)
| 
| More problematic:
| 
| * TAHI cooperation/IPv6 testing
| * TIPC testing
| * application loading (done, but not accepted by glibc?)
| 
| * IPv6:
|   - glibc -- e.g., getifaddrs() needed by DHCPv6 (hosted by OSDL)
|     ported from BSD, but haven't been pushed to glibc maintainers yet
| 
| -----
| 
| Red flag items:
| 
| * AEM
| * boot cycle detection
| * live SW upgrade
| * resource monitoring
| * OpenHPI still waiting on SAF/legal stuff; resources expected to be
|   available (probably all non-kernel)

Hi Andy,

(bottom-posting here :)

I agree that sar is important.  What version(s) are you aware of
for 2.5?  Do you know about the updates at <http://linux.inet.hr/> ?
and not only those at <http://perso.wanadoo.fr/sebastien.godard/> ?
and patches at <http://www-124.ibm.com/linux/patches/?project_id=145> ?

However, keeping it up-to-date for 2.5 is a good (even admirable) goal,
since it's quite a moving target.

Thanks,
