_ctl_do_mpt_command(9)

💅 _ctl_do_mpt_command — the main handler for the MPT3COMMAND opcode ✨

okay so first things first, bestie: this is a page from the Kernel API Manual (yes, the kernel has a manual, it's giving official 👑) and today's main character is _ctl_do_mpt_command. she's the one who handles the MPT3COMMAND opcode. no cap, that's literally her whole job title 🎀

🌸 SYNOPSIS 🌸

long _ctl_do_mpt_command (struct MPT3SAS_ADAPTER *ioc , struct
mpt3_ioctl_command karg , void __user *mf );

like, she takes three things and returns a long. iconic signature fr fr 🫶

✨ ARGUMENTS ✨

• ioc — the per adapter object 💖. that's your adapter's own little world, her whole personality.
• karg — a (struct mpt3_ioctl_command). yes the type is in parens, we love a well-labeled parameter 🙈
• mf — a pointer to mf, and plot twist: that mf lives in user space 👀 so like, be normal about it.

🦋 SEE ALSO 🦋

okay this list is lowkey a whole friend group 😭 everyone in it gets a (9) because they're all kernel API pages. the kernel file lives at ./drivers/scsi/mpt3sas/mpt3sas_ctl.c and honestly the roster is long, so buckle up buttercup:

like… that's the whole function family reunion and everyone showed up 💀 every single _show and _store, all the diag stuff, all the btdh lookups, the compat twins, the mpt2 variants — nobody left out, periodt 🌈

real talk though bestie: she's taking a pointer from user space (mf), so this is one of those "trust but verify" moments. handle with care, okay? 🫶
