ubifs_gc_should_commit(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ubifs_gc_should_commit — the kernel API manual, bestie edition 🎀

okay so this is ubifs_gc_should_commit(9) from the Kernel API Manual, and no cap, it's a tiny little vibe check for garbage collection. let's get into it ✨

✨ NAME ✨

ubifs_gc_should_commit — literally the function that figures out if it's time for GC to run commit. that's it. that's the whole job 🫶

🌸 SYNOPSIS 🌸

int ubifs_gc_should_commit (struct ubifs_info *c );

like, exactly that. no extra bits, no sneaky params 💅

🦋 ARGUMENTS 🦋

  • c — the UBIFS file-system description object. your whole filesystem's little personality profile, basically 👑

🔥 DESCRIPTION 🔥

so here's the tea: garbage collection calls this function to decide whether commit should be run. yes, GC is out here asking for permission, main character energy fr fr.

if the commit state is COMMIT_BACKGROUND — which means the journal is full enough to start commit — this function returns true. and like, is it absolutely necessary to commit yet? no bestie, it is not. but it lowkey feels like this should be better then to keep doing GC. the vibe is: wrap it up, we're committing 🌈

so, to be super clear on the return value (iykyk, this is the part you actually need):

  • returns 1 if GC has to initiate commit 💖
  • returns 0 if not 🙈
