2.6.6 was released on May 10, 2004 changelog

• Per-backing dev unplugging (LWN article) commit

• CFQ io scheduler, tries to distribute bandwidth equally among all processes in the system. It should provide a fair working environment, suitable for desktop systems. Recommended LWN article. commit

• Add Laptop Mode: a special sysctl which says "this is a laptop". In this mode the kernel will attempt to avoid spinning disks up (LWN article) commit

• ext2/3: Speed up fsync(2) for file overwrites by a factor of four (disk non-writeback) to forty (disk in writeback mode) commit, commit

• lockfs (file system freezing), taken from XFS commit, commit, commit

• The lightweight auditing framework (LWN article). commit

• SELinux: add IPv6 support commit, commit

• selinux: add runtime disable commit

• Prepare the kernel for a full object-based reverse-mapping scheme and the removal of the per-page PTE chains. Recommended LWN article commit, commit, commit

• Non-Exec stack support commit

• POSIX Message Queues: POSIX variant of message queues is a part of IPC. In POSIX message queues every message has a priority which decides about succession of receiving it by a process commit, commit, commit, commit, commit, commit, commit

• TCP: BIC TCP, Binary Increase Control TCP developed by NCSU. It is another TCP congestion control algorithm for handling big fat pipes. For normal size congestion windows it behaves the same as existing TCP Reno, but when window is large it uses additive increase to ensure fairness and when window is small it uses binary search commit

• TCP: Add vegas congestion avoidance support commit, commit
