megasas_set...cpu_affinity(9)

✨ NAME ✨

okay so bestie, welcome to the Kernel API Manual 💖 this page is all about megasas_set_raidflag_cpu_affinity — the function that sets the CPU affinity (yes, the CPU of the controller, not your random little userspace CPU) and the raid_flags in the raid context, based on the IO type. periodt. 💅

💅 SYNOPSIS 💅

void megasas_set_raidflag_cpu_affinity (struct fusion_context *fusion ,
union RAID_CONTEXT_UNION *praid_context , struct MR_LD_RAID *raid , bool
fp_possible , u8 is_read , u32 scsi_buff_len );

it returns void, so there is literally no return value to collect — it's giving “do the thing and dip” energy ✨

🫶 ARGUMENTS 🫶

• fusion — the Fusion context 🌀
• praid_context — the IO RAID context 💾
• raid — the LD raid map 🗺️
• fp_possible — is fast path possible? 👀
• is_read — is this a read IO? 📖
• scsi_buff_len — the SCSI command buffer length 📏
