💖 ubifs_log_end_commit(9) — the Kernel API Manual glow-up 💖

okay bestie, so this is ubifs_log_end_commit, from the Kernel API Manual (section 9 ofc), and it is literally the "closing the group chat" function of UBIFS. Come sit, I'll explain everything 🫶

✨ NAME ✨

ubifs_log_end_commit — end commit. that's it, that's the whole vibe. short, iconic, to the point 👑

🦋 SYNOPSIS 🦋

int ubifs_log_end_commit (struct ubifs_info *c , int ltail_lnum );

yes the spaces before the commas are canon, don't come for me 💅

🎀 ARGUMENTS 🎀

  • c — the UBIFS file-system description object. the whole personality of the filesystem lives in here fr.
  • ltail_lnum — new log tail LEB number. this is the new spot, the fresh address, the glow-up location ✨

🌸 DESCRIPTION 🌸

so here's the tea: this function gets called when the commit operation was finished. like, wrap-party time, the commit is DONE, everybody go home 🎉

what it does is genuinely so satisfying: it moves the log tail to a new position and then updates the master node so that the master node stores the new log tail LEB number. the way it just relocates and re-records... lowkey main character energy 👑

and the return sitch? it returns zero in case of success, and a negative error code in case of failure. zero = slay, negative = 😭

ngl bestie, if you get a negative error code back, that is your signal to go investigate. fr fr. the function is telling you something went wrong and you should not just vibe past it 💀
