Version 2 --------- * Integrate review comments (see change log of single patches) * Add sysctl to switch to new behavior instead of adding the additional cdata_acct to struct signal (see patch 3) Due to POSIX POSIX.1-2001, the CPU time of processes is not accounted to the cumulative time of the parents, if the parents ignore SIGCHLD or have set SA_NOCLDWAIT. This behaviour has the major drawback that it is not possible to calculate all consumed CPU time of a system by looking at the current tasks. CPU time can be lost. This patch series adds a new sysctl "full_cdata" that allows to switch the kernel to a mode where also the missing data is accounted to the cumulative counters.
