Subject: [STATUS 2.5] June 19, 2002
Date: Wed, 19 Jun 2002 00:09:18 -0400 [thread overview]
Message-ID: <3D0FCBAE.12064.252B48B2@localhost> (raw)
With the kernel summit next week in Ottawa, I figured I would look back
on the last six months of development. Much has happened!
Of the items that were discussed at the last Kernel Summit and are being
taken care of (most still need more work but the bulk is there):
- Block IO: merged
- NAPI: merged
- LDM & driverfs: merged
- ACPI: merged
- hotplug: merged
Among the most 'important & not yet merged' items - at least the ones I
have received the most requests about from people :-)
- kbuild 2.5: should be integrated soon in pieces
- AIO: some pieces are just starting to get merged
- VM: not merged
- LSM: not merged
- XFS: not merged
- initramfs: not merged
As usual, the URL with the details is http://www.kernelnewbies.org/status/
Enjoy!
