_base_get_ma...iag_triggers(9)

🦋 NAME 🦋

okay so welcome to the Kernel API Manual bestie 💖 — this page's header got cut off mid-sentence (it literally reads _base_get_ma...iag_triggers(9), the drama 😭), but the actual star of the show is:

_base_get_master_diag_triggers — she gets the master diag trigger values from the persistent pages ✨ periodt, that's the whole gig.

---

🌸 SYNOPSIS 🌸

int _base_get_master_diag_triggers (struct MPT3SAS_ADAPTER *ioc );

like yes that's it, that's the signature, keep the space before the ) exactly as-is, no cap 🫶

---

🎀 ARGUMENTS 🎀

• ioc — the per adapter object 💅 like, the one adapter this whole thing is about. hand her over and that's it.

---

⭐ RETURN ⭐

nothing. literally nothing. she returns nothing. — not zero, not an error code, nothing 🙈 the function does her thing and does not report back. main character energy honestly 👑

side note bestie: _base_get_event_diag_triggers(9), _base_get_scsi_diag_triggers(9) and _base_get_mpi_diag_triggers(9) are literally her sibling functions — the trigger squad 🔥 go read those next, iykyk.
