_ctl_diag_get_bufftype(9)

okay bestie, welcome to _ctl_diag_get_bufftype(9) from the Kernel API Manual 💅 — this page is short and it knows it.

🌸 NAME

_ctl_diag_get_bufftype — returns the diag buffer type, and that type is either TRACE, SNAPSHOT, or EXTENDED. That's the name-section vibe, no cap. ✨

✨ SYNOPSIS

u8 _ctl_diag_get_bufftype (struct MPT3SAS_ADAPTER *ioc , u32 unique_id
);

that's the exact signature, bestie — spacing and line break included, don't touch it 🫶

🫶 ARGUMENTS

• ioc — per adapter object 🌟
• unique_id — specifies the unique_id for the buffer 🎀

💅 DESCRIPTION

it returns MPT3_DIAG_UID_NOT_FOUND if the id not found. that's the whole description — tiny, specific, and giving very important kernel-helper energy 💀
