The most notable change in this series is the removal of the interrupt handle duplication. I concluded the principle is wrong (see patch 2 commitlog). This will need some careful reviews. -- David Marchand Changes since v1: - added Anatoly fixes which also extend the interrupt check to efds https://patchwork.dpdk.org/project/dpdk/list/?series=39788&state=* Anatoly Burakov (3): eal/linux: fix closing of event FDs not owned by EAL eal/linux: fix eventfd leaks when enabling interrupts interrupts: warn on leaked event FDs David Marchand (7): eal/linux: reset FD in interrupt handle for uevent interrupts: do not duplicate interrupt handles net/mana: reset FD in interrupt handle net/memif: fix some interrupt FD leaks net/memif: reset FD in interrupt handle net/sxe2: reset FD in interrupt handle raw/ifpga: reset FD in interrupt handle Stephen Hemminger (2): eal/linux: fix FD leak in alarm subsystem bus/pci: reset VFIO device FD after release doc/guides/rel_notes/release_26_11.rst | 1 + drivers/bus/pci/linux/pci_vfio.c | 4 +- drivers/common/cnxk/roc_platform.h | 1 - drivers/net/mana/mana.c | 4 ++ drivers/net/memif/memif_socket.c | 28 ++++++-- drivers/net/sxe2/sxe2_irq.c | 2 + drivers/raw/ifpga/ifpga_rawdev.c | 2 + lib/eal/common/eal_common_interrupts.c | 31 ++------- lib/eal/freebsd/eal_interrupts.c | 17 ++--- lib/eal/include/rte_interrupts.h | 24 ++----- lib/eal/linux/eal_alarm.c | 1 + lib/eal/linux/eal_dev.c | 4 +- lib/eal/linux/eal_interrupts.c | 94 +++++++++++++++----------- 13 files changed, 109 insertions(+), 104 deletions(-) -- 2.54.0
