mpi3mr_fwevt_free(9)

📦 version 7.3.1, in nixpkgs unstable

💅 mpi3mr_fwevt_free — like, the Kernel API Manual page for it ✨

okay bestie, gather round, because today we're reading a man page from the Kernel API Manual and honestly? she's short but she matters. This is mpi3mr_fwevt_free(9), and yes the (9) means she's kernel-internal royalty 👑

🎀 NAME 🎀

mpi3mr_fwevt_free — the firmware event memory deallocator 🧹✨

like, she's the one who cleans up after the party. no cap.

🦋 SYNOPSIS 🦋

void mpi3mr_fwevt_free (struct kref *r );

that's it. that's the whole signature. she's void, she takes one pointer, she does not return anything because she's done when she's done 💅

🌸 ARGUMENTS 🌸

  • r — the kref reference pointer of the firmware event 🫶 (yes, that's the k reference pointer of the firmware event, exactly like it sounds — a pointer to the struct kref living inside the firmware event)

✨ DESCRIPTION ✨

Free the firmware event memory when no reference remains. 🧚

that's the whole vibe: the refcount hits zero, the reference is gone, and then she frees the memory. not before. don't be out here freeing things that still have refs, i am literally begging 🙈

🔥 SEE ALSO 🔥

okay this is the part where the page goes absolutely feral with cross-references, and we are NOT skipping a single one, because every single one is iconic in her own way 👑

the source file (iykyk):

  • Kernel file ./drivers/scsi/mpi3mr/mpi3mr_os.c

and the whole extended friend group 💖:

bestie that's the whole guest list and every single one of them ate 💅

reminder: she frees the firmware event memory when no reference — so mind your krefs, or it's giving use-after-free 💀

🎀 sign-off 🎀
