state_change(9)

💅 state_change — NAME 💅

okay so state_change — it's the little function that records that the glock is now in a different state. that's it, that's the whole job. she's the notary public of glock state changes, and honestly? iconic. 🎀

(this whole page lives in the Kernel API Manual, section 9, iykyk 🦋)

✨ SYNOPSIS ✨

void state_change (struct gfs2_glock *gl , unsigned int new_state );

🌸 ARGUMENTS 🌸

• gl — the glock. yeah. that one. the glock in question 👑
• new_state — the new state. the state she's changing to. the fresh vibe she's stepping into ✨
