Subject: [STATUS 2.5] March 20, 2002
Date: Wed, 20 Mar 2002 11:39:12 -0500 [thread overview]
Message-ID: <3C9874E0.14526.3D4235FF@localhost> (raw)
The latest status update for the 2.5 series is available at
http://kernelnewbies.org/status/ with links for each item.
Of note since last week is the merge of NAPI, which is a way
to deal with high network packet load -- networking drivers
authors may want to take a look at the porting guide.
Also merged is a big ACPI patch, which should pave the way
for better power management in Linux.
As usual, please let me know of anything incorrect or missing.
Cheers,
-- Guillaume
