💅 mei_cl_read_cb(9) — aka the Kernel API Manual glow-up 🎀

okay so bestie, welcome to the mei_cl_read_cb(9) page 💖 this is a genuine kernel API manual entry, and we're about to make it make sense. no cap.

✨ NAME ✨

mei_cl_read_cb — find this cl's callback in the read list for a specific file 🦋

like, you hand it a client and a file, and it goes digging through the read list to find the callback that matches. that's the whole vibe check. 💅

🌸 SYNOPSIS 🌸

struct mei_cl_cb * mei_cl_read_cb (struct mei_cl *cl , const struct file *fp );

literally just those two args, bestie. nothing sneaky. 🫶

💜 ARGUMENTS 💜

  • cl — host client 👑 this is the struct mei_cl * we're searching on behalf of.
  • fp — file pointer (matching cb file object), may be NULL 🙈 yes, NULL is allowed here. icon behaviour honestly.

⭐ RETURN ⭐

cb on success 🎉 — and NULL if cb is not found 😭 that's it, that's the whole return contract. no secret bonus values. periodt.

🌈 SEE ALSO 🌈

okay this list is long and every single one of these is part of the family, so we're listing all of them, no skipping, no "etc." energy 👑

also pointing you at the kernel file ./drivers/misc/mei/client.c if you wanna go read the source with your own two eyes 💖

ngl that's a whole friend group 😭 but they're all closely related mei client + io callback functions, so if you're reading one you're probably gonna want the others. iykyk 💀

and that's the page!! 🧚 this one's from ./drivers/misc/mei, dated October 2026 — mwah, iconic, no notes 💋✨🍓

🫶 bye bestie 🫶
