This patch fixes a lockdep issue created due to ixgbe_ptp_stop always running cancel_work_sync even if the work item had not been created properly with INIT_WORK. This is caused because ixgbe_ptp_stop did not check to actually ensure PTP was running first. The new implementation introduces a state in the &adapter->state field which is used to indicate that PTP is running. (This replaces the IXGBE_FLAG2_PTP_ENABLED field). This state will use the atomic set_bit, test_bit, and test_and_clear_bit functions. ixgbe_ptp_stop will check to ensure that PTP was enabled, (and if not, it will not attempt to do any cleanup work from ixgbe_ptp_init). This resolves the lockdep annotation warning found by Stephen Hemminger Reported-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Acked-by: Don Skidmore <donald.c.skidmore@intel.com> Tested-by: Phil Schmitt <phillip.j.schmitt@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> |
