[KLUG Members] Kernel 2.5.68

[Peter Buxton]

Call me lazy, but I haven't had a chance yet to compare the Red Hat 2.4
kernel to the stock Linus 2.5.x. I did just sit down and compare just
now, though, and I note the following differences:

Where is the 2.4 XFS .config option? in 2.5.x it's CONFIG_XFS_FS. Also,
CONFIG_FS_POSIX_ACL is gone, probably because it's integrated in 2.5.x.

Advanced Linux Sound Architecture (ALSA): is in 2.5.x, but not RH 2.4.

Kernel Preemption: in 2.5.x. RH's 2.4 has the complementary low-latency
patch.

ACPI: It's in 2.5.x, but immature.

Enterprise Volume Management System: in RH 2.4, not in 2.5.x. Linus and
Alan Cox sent EVMS back down to the team for redesigning.

Stream Control Transmission Protocol (SCTP): SCTP is a peer to TCP and
UDP and depends only upon IP and IP dependencies, e.g., ICMP.  Unlike
TCP, which transmits bytes, SCTP transmits discrete messages in
separate, asynchronous sessions over a single SCTP reliable vitual
circuit:

Cryptographic and Linux Security Modules: 2.5.x comes with support for
encrypted file systems (a la NTFS) and modular support for such systems
as LIDS.

Section Speakup 508 (???) and Linux ABI: in Red Hat only. Hm.

the field is laying down a good line of suppressive fire.
