ima_inode_post_setattr — reflect file metadata changes

🦋 SYNOPSIS 🦋

void ima_inode_post_setattr (struct mnt_idmap *idmap , struct dentry *dentry , int ia_valid );

---

🎀 ARGUMENTS 🎀

• idmap — the idmap of the mount the inode was found from. iykyk 🫶
• dentry — pointer to the affected dentry, like the actual entry getting noticed 👀
• ia_valid — for the UID and GID status. that’s the vibe check for this one 💅

---

✨ DESCRIPTION ✨

so when a dentry’s metadata changes, that might mean we need to appraise something. yes really, metadata glow-ups can trigger appraisal 😭

this function gets called from notify_change, which expects the caller to lock the inode’s i_mutex.

bestie, lock that i_mutex — the caller is expected to do it, no cap 🔒
