= 2.6.10 =
  * Released December 24, 2004 [[http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.10|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 [[http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=fa4c8b605c3313de9e3170b68b9e4576a6a5d45e|(commit)]]
  * x86-64 clustered APIC support [[http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=7f8b8c2a84d1098aec520d1f701c752f10bc5396|(commit)]]
  * Make rlimit settings per-process instead of per-thread for POSIX compliance [[http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=f1a81f9149ac2321978e1357eb697f95cc31e989|(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 [[http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=99ae4bcef104d602d790eb7da7cfc241ca6eefee|(commit)]]
