[PATCH 16/39] autonuma: call autonuma_setup_new_exec()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

This resets all per-thread and per-process statistics across exec
syscalls or after kernel threads detached from the mm. The past
statistical NUMA information is unlikely to be relevant for the future
in these cases.
