The first improves reset code to allow linkwatch_event to proceed during reset. The second ensures that no more than one thread runs in reset at a time. v2: - Separate change param reset from do_reset() - Return IBMVNIC_OPEN_FAILED if __ibmvnic_open fails - Remove setting wait_for_reset to false from __ibmvnic_reset(), this is done in wait_for_reset() - Move the check for force_reset_recovery from patch 1 to patch 2 v3: - Restore reset’s successful return in open failure case v4: - Change resetting flag access to atomic Juliet Kim (2): net/ibmvnic: unlock rtnl_lock in reset so linkwatch_event can run net/ibmvnic: prevent more than one thread from running in reset drivers/net/ethernet/ibm/ibmvnic.c | 262 ++++++++++++++++++++++++++----------- drivers/net/ethernet/ibm/ibmvnic.h | 6 +- 2 files changed, 190 insertions(+), 78 deletions(-) -- 2.16.4
