int megasas_issue_tm (struct megasas_instance *instance , u16 device_handle , uint channel , uint id , u16 smid_task , u8 type , struct MR_PRIV_DEVICE *mr_device_priv_data );

🎀 ARGUMENTS 🎀

• instance — per adapter struct, bestie 🫶
• device_handle — device handle ✨
• channel — the channel assigned by the OS 🌈
• id — the id assigned by the OS ⭐
• smid_task — smid assigned to the task 💅
• type — MPI2_SCSITASKMGMT_TASKTYPE__XXX (defined in megaraid_sas_fusion.c) 🔥
• mr_device_priv_data — private data 🎀

🦋 CONTEXT 🦋

Context: user 👑 — yes, that is the whole context, periodt.
