But the\ncurrent coverage of that API is spotty. Many internal parts of\nDPDK leave files and allocated memory behind.\n\nThis patch set is a start at getting the sub-parts of\nDPDK to cleanup after themselves. These are the easier ones,\nthe harder and more critical ones are in the drivers\nand the memory subsystem.\n\nThere are no visible API or ABI changes here.\n\nStephen Hemminger (14):\n eal: log: close on cleanup\n eal: log: free dynamic state on cleanup\n eal: alarm: close timerfd on eal cleanup\n eal: cleanup threads\n eal: intr: cleanup resources\n eal: mp: end the multiprocess thread during cleanup\n eal: interrupts close epoll fd on shutdown\n eal: vfio: cleanup the mp sync handle\n eal: close mem config on cleanup\n tap: close netlink socket on device close\n eal: cleanup plugins data\n ethdev: raise priority of old driver warning\n eal: hotplug: cleanup multiprocess resources\n eal: malloc: cleanup mp resources\n\n drivers/net/tap/rte_eth_tap.c | 7 ++++-\n lib/librte_eal/common/eal_common_log.c | 30 +++++++++++++++++-\n lib/librte_eal/common/eal_common_options.c | 12 +++++++\n lib/librte_eal/common/eal_common_proc.c | 17 +++++++---\n lib/librte_eal/common/eal_options.h | 1 +\n lib/librte_eal/common/eal_private.h | 30 ++++++++++++++++++\n lib/librte_eal/common/hotplug_mp.c | 5 +++\n lib/librte_eal/common/hotplug_mp.h | 6 ++++\n lib/librte_eal/common/malloc_heap.c | 6 ++++\n lib/librte_eal/common/malloc_heap.h | 3 ++\n lib/librte_eal/common/malloc_mp.c | 12 +++++++\n lib/librte_eal/common/malloc_mp.h | 3 ++\n lib/librte_eal/linux/eal/eal.c | 28 +++++++++++++++++\n lib/librte_eal/linux/eal/eal_alarm.c | 11 +++++++\n lib/librte_eal/linux/eal/eal_interrupts.c | 35 ++++++++++++++++++---\n lib/librte_eal/linux/eal/eal_log.c | 14 +++++++++\n lib/librte_eal/linux/eal/eal_vfio.h | 1 +\n lib/librte_eal/linux/eal/eal_vfio_mp_sync.c | 8 +++++\n lib/librte_ethdev/rte_ethdev.c | 2 +-\n 19 files changed, 218 insertions(+), 13 deletions(-)" }
