Subject: [STATUS 2.5] January 23, 2002
Date: Wed, 23 Jan 2002 01:23:39 -0500
Lots of new things this week. First, a new URL that (yes!) people can
bookmark:
http://www.kernelnewbies.org/status/status.html
Many thanks to John Levon, Rik van Riel and the folks at kernelnewbies.org
for providing the hosting! You guys rock.
Also, lots of new features (in bold) have been added this week. Hopefully,
most of the *truly* important stuff should be in the list now, maybe except
a few things (nfs4? scsi?). Otherwise, if more features get added than
merged any given week, 2.5 is going to be long in the coming :-)
Finally, I have to admit the amount of feedback I have received has been
incredible and has helped improve this list dramatically, so big thanks
to everyone who has sent me pointers, keep doing it. My main concern right
now is to keep this status list to a reasonnable size, otherwise it will
become unmanageable. My plan is pretty simple, I will only accept:
1. A major feature, i.e. *lots* of people are anxious to get this in the
2.5 tree because they will use it (i.e kbuild or NAPI)
OR
2. A feature/cleanup that touches critical parts of the kernel and
requires lots of people to know about it because they will be affected
--> i.e. good communication of status is important (i.e some of the
VFS work).
In short, don't bother sending me driver updates...
And as usual, let me know of any inaccuracies, and I'll be happy to
correct them.
Cheers,
-- Guillaume
