locks_owner_has_blockers(9)

💅 locks_owner_has_blockers(9) 💅

okay so this is a page straight out of the Kernel API Manual, and honestly? it's a lil baby function but it's an icon. it just wants to know one thing: is anybody out here blocking your lock requests, bestie? that's it. that's the whole vibe check. 🎀

✨ NAME ✨

locks_owner_has_blockers — check for blocking lock requests, fr fr 🫶

---

✨ SYNOPSIS ✨

bool locks_owner_has_blockers (struct file_lock_context *flctx ,
       fl_owner_t owner );

so you call it like that, okay? noted. moving on. 💅

---

✨ ARGUMENTS ✨

• flctx — the file lock context, aka the whole situation we're looking at here 🦋
• owner — the lock owner, aka who we're asking about 👑

---

✨ DESCRIPTION ✨

okay so literally all this does is tell you the return values, and here they are, no cap:

• true: the owner has at least one blocker 😭 like there is someone in the way
• false: the owner has no blockers ✨ clean slate, main character energy, nothing standing between them and their lock

that's the whole function. short queen behavior. lowkey obsessed with how simple it is. 🌸
