Nicholas Bellinger 80bfdfa924 target/pr: Use atomic bitop for se_dev_entry->deve_flags reservation check ... This patch converts the core_scsi3_pr_seq_non_holder() check for non reservation holding registrations to use an atomic bitop in ->deve_flags to determine if a registration is currently active. It also includes associated a set_bit() in __core_scsi3_add_registration() and clear_bit() in __core_scsi3_free_registration(), if se_dev_entry still exists, and has not already been released via se_dev_entry shutdown path in core_disable_device_list_for_node(). Also, clear_bit in core_disable_device_list_for_node as well to ensure the read-critical path in core_scsi3_pr_seq_non_holder() picks up the new state, preceeding the final kfree_rcu() call.
