STRUCT LANDLOCK_SUPERBLOCK_SECURITY(9)

💖 NAME 💖

okay so bestie, this is the Kernel API Manual and we are literally looking at struct landlock_superblock_security — it's the superblock security blob, no cap 🫶

✨ SYNOPSIS ✨

here's the whole vibe, exactly as it slays in the source:

struct landlock_superblock_security {
    atomic_long_t inode_refs;
 };

🎀 Members 🎀

• inode_refs — this is the count of pending inodes (ones from this superblock, iykyk) that release_inode is still in the middle of releasing. Basically a little "how many are still in flight" tally. Cf. struct super_block->s_fsnotify_inode_refs .

🦋 Description 🦋

the whole point of this struct? it lets hook_sb_delete wait for concurrent calls to release_inode to finish 😭 no more racing ahead while stuff is still being cleaned up — it's giving responsible main character energy.

and that's the whole page, periodt ✨ this masterpiece lives in ./security/landlock, it's dated October 2026, and it's from the Kernel API Manual — go off, kernel docs, you ate 🌸🎀💜
