💅 _drbd_set_state(9)

okay so bestie, welcome to the Kernel API Manual ✨ — yes, the kernel one, we're doing big-girl kernel vibes today 🎀 this page is all about _drbd_set_state, lowercase underscore and all, do not @ me about the underscore, it's part of the name 💀

🌸 NAME 🌸

_drbd_set_state — set a new DRBD state 🦋 like, it literally changes the state, iconic behaviour, no notes

✨ SYNOPSIS ✨

enum drbd_state_rv _drbd_set_state (struct drbd_device *device , union
drbd_state ns , enum chg_state_flags flags , struct completion *done );

look at that signature, it's giving main character energy 👑

🎀 ARGUMENTS 🎀

  • device — the DRBD device 💖 that's the thing we're messing with, keep your eyes on it
  • ns — the new state 🌈 literally "ns" as in new state, so fresh, so slay
  • flags — flags 🚩 yes, flags, the little switches that change how things go down
  • done — optional completion, that will get completed after the after_state_ch finished ⭐ like it pings you when the clean-up era is officially over, optional bestie, optional 🫶

🔥 DESCRIPTION 🔥

Caller needs to hold req_lock 💅 no cap, that's a hard requirement — hold the lock or don't come to the function.

Do not call directly. 🙈 seriously, do not call this one directly, it's an internal vibe, go through the proper doors, iykyk

bestie pls respect the lock and the "do not call directly" — this is not a suggestion, this is the whole point 😭💀
