[PATCH] csa: basic accounting over taskstats Add some basic accounting fields to the taskstats struct, add a new kernel/tsacct.c to handle basic accounting data handling upon exit. A handle is added to taskstats.c to invoke the basic accounting data handling.

Netlink messages are delivered syncrhonously to the kernel allowing us to get the user namespace and the pid namespace from the current task. - Pass the namespaces for representing pids and uids and gids into bacct_add_task.

[PATCH] csa: convert CONFIG tag for extended accounting routines There were a few accounting data/macros that are used in CSA but are #ifdef'ed inside CONFIG_BSD_PROCESS_ACCT. This patch is to change those ifdef's from CONFIG_BSD_PROCESS_ACCT to CONFIG_TASK_XACCT. A few defines are moved from kernel/acct.c and include/linux/acct.h to kernel/tsacct.c and include/linux/tsacct_kern.h.

While remotely reading the cputime of a task running in a full dynticks CPU, we'll need to do some extra-computation. This way we can account the time it spent tickless in userspace since its last cputime snapshot.
