_scsih_issu...io_unit_ctrl(9)

💖 NAME 💖

Okay bestie, welcome to the Kernel API Manual page for _scsih_issue_delayed_sas_io_unit_ctrl(9) — yes, the whole mouthful. The header lowkey shortens it to _scsih_issu...io_unit_ctrl(9), but the actual name is the full thing. This function issues delayed sas_io_unit_ctrl messages. ✨

🌸 SYNOPSIS 🌸

void _scsih_issue_delayed_sas_io_unit_ctrl (struct MPT3SAS_ADAPTER *ioc
, u16 smid , u16 handle );

🦋 ARGUMENTS 🦋

• ioc — the per-adapter object, your little controller bestie 🫶
• smid — system request message index, iykyk
• handle — device handle

🎀 DESCRIPTION 🎀

Context check: this one is processed in interrupt context. That's the vibe. 💅
