✨ fillup_metapath(9) — the glow-up guide ✨

okay so bestie, welcome to the kernel API manual, and today's main character is fillup_metapath 💅 it's literally a kernel function for GFS2 and it's giving "i handle metadata paths at specific heights," so let's get into it 🎀

🌸 SYNOPSIS 🌸

int fillup_metapath (struct gfs2_inode *ip , struct metapath *mp , int h
);

like, that's the whole signature — short, iconic, no notes ✨

💖 ARGUMENTS 💖

  • ip — The inode 👑 bestie this is the inode we're working with, the whole reason we're here.
  • mp — The metapath 🦋 this is the metapath buffer situation itself.
  • h — The height to which it should be mapped 📏 literally the height, that's the assignment.

🧚 DESCRIPTION 🧚

So the tea is: this function is similar to lookup_metapath, but instead of doing the lookup at one single height, it does lookups for a range of heights 🔥 it's like lookup_metapath's extroverted sibling who can't just do one thing — it fills up buffers for the metadata path to a specific height, no cap ✨

🌈 RETURN 🌈

It returns an error or the number of buffers filled 💀 so like, either something went wrong or you get a cute little count of how many buffers got filled. vibe check either way 🫶
