Patch 1 takes care of a common resource leak in various error paths, while the second patch fixes a misordered kfree when cleaning up after an error. The other two patches ensure that there's no stale work dangling on workqueues when the qeth device has already been offlined and/or removed. Thanks, Julian Julian Wiedmann (4): s390/qeth: release cmd buffer in error paths s390/qeth: fix use-after-free in error path s390/qeth: cancel close_dev work before removing a card s390/qeth: conclude all event processing before offlining a card drivers/s390/net/qeth_core.h | 3 ++- drivers/s390/net/qeth_core_main.c | 31 ++++++++++++++++++++----------- drivers/s390/net/qeth_l2_main.c | 8 ++++++-- drivers/s390/net/qeth_l3_main.c | 3 +++ 4 files changed, 31 insertions(+), 14 deletions(-) -- 2.16.4
