mpi3mr_flush_drv_cmds(9)
π mpi3mr_flush_drv_cmds β from the Kernel API Manual, bestie β¨
okay so this is a page from the Kernel API Manual (yes, the Kernel API Manual, that's the manual name, we're citing our sources π) and it's about one tiny little function that does one big little job. it's giving "small but mighty", it's giving "cleanup crew main character energy". let's get into it π
β¨ NAME β¨
mpi3mr_flush_drv_cmds β Flush internaldriver commands π½β¨ (and yes, "internaldriver" is written exactly like that, one word, no cap, I'm not fixing it, that's how it lives in the manual π)
π¦ SYNOPSIS π¦
void mpi3mr_flush_drv_cmds (struct mpi3mr_ioc *mrioc );
literally one argument, one return type of void, no drama. the way this signature just sits there being all minimal π
πΈ ARGUMENTS πΈ
mriocβ the adapter instance reference π«Ά like, it wants a pointer to thestruct mpi3mr_ioc, that's the whole ask. that's the vibe check. hand it your adapter instance and you're good π
π₯ DESCRIPTION π₯
it flushes all internal driver commands, and it does this post reset π«
that's it. that's the whole description. sometimes the icon behavior is just being unambiguous, y'know? no extra lore, no side quests, just: reset happens, then the internal driver commands get flushed. periodt. π
β οΈ quick little note bestie β the manual says "post reset", so like, that's the context it exists in. it's not claiming to do anything else, and neither am I π
β RETURN β
Nothing. π«§ as in void, as in it gives you zero things back, as in it's not about the return value, it's about the journey. ngl a function that just does the thing and leaves is so lowkey iconic π
π SEE ALSO π
okay this is where it gets unhinged in the best way β the SEE ALSO section is a whole friend group, a full group chat, an entire roster π and there's one specific file mentioned first:
Kernel file ./drivers/scsi/mpi3mr/mpi3mr_fw.c β that's the house these functions all live in π π
and now, the full squad, in order, no one left behind, everyone gets an invite to the party:
