2.6.10

• Released December 24, 2004 changelog

• Accounting: report single record for multithreaded process. In kernels before 2.6.10, a separate process accounting record was written for each thread created using NTPL. Since 2.6.10, a single accounting record is written for the entire process (commit)

• x86-64 clustered APIC support (commit)

• Make rlimit settings per-process instead of per-thread for POSIX compliance (commit)

• POSIX compliant CPU clocks (commit)

• Show aggregate per-process counters in /proc/$PID/stat: Add up resource usage counters for live and dead threads to show aggregate per-process usage. This mirrors the new getrusage() semantics. /proc/$PID/task/$TID/stat still has the per-thread usage (commit)

• Report the pages used for pagetables in /proc/$PID/status (commit)

• Display committed memory limit (per the current overcommit ratio) and the amount of memory remaining under this limit in meminfo (commit)

• Thrashing control tuning (commit)

• Big Kernel Lock preemption

• IRQ subsystem code rework (commit)

• Removal of the "BIO walking" helper functions

• Generic circular buffer type (LWN article) (commit)

• Ext3 block reservation (LWN article) (commit)

• Ext3 online resizing patches (LWN article) (commit)

• Add I/O error handling to journal operations in reiserfs (commit)

• sysfs backing store (LWN article)

• I/O space write barriers (LWN article) (commit)

• Modular, on-the-fly switchable I/O schedulers (LWN article) (commit)

• CFQ v2 update (commit)

• BSD secure levels module (commit)

• In-kernel cryptographic key management (commit)

• DVD+RW support (commit)

• CDRW packet writing support (commit)

• kernel events notification mechanism

• Lock initializater unification (commit)

• Panick blinking: Makes the keyboard blink when a oops happens - useful to know if the kernel has really oopsed or not (ej: X.org bugs) (commit)

• Reworking of spin lock initialization (LWN article)

• Configurable /proc/kcore (commit)
