ima_post_create_tmpfile(9)

💅 ima_post_create_tmpfile — like, the Kernel API Manual page, bestie ✨

okay so real talk, this is ima_post_create_tmpfile(9) from the Kernel API Manual, and it's honestly a tiny little icon. she doesn't do much but she matters. let's get into it 🫶

---

🌸 NAME 🌸

ima_post_create_tmpfile — mark a newly created tmpfile as new 🎀

---

✨ SYNOPSIS ✨

void ima_post_create_tmpfile (struct mnt_idmap *idmap , struct inode
*inode );

that's it. that's the whole vibe. no return value, she just does the thing and dips 💅

---

🦋 ARGUMENTS 🦋

• idmap — the idmap of the mount that the inode was found from. like, which mount did this inode come from, bestie? this tells you 🔍
• inode — the inode of the newly created tmpfile. the main character herself 👑

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — for newly created tmpfiles, there is no measuring, no appraising, and no auditing needed. none. zero. not the vibe. so we skip calling process_measurement entirely, no cap.

but!! (and this is the important part) we do still need to indicate which newly created tmpfiles are in policy. so she's not doing nothing — she's marking them, lowkey. 🎀

bestie pls don't skip the "in policy" part, that's literally the whole point of the function 😭
