🦋 ceph_cls_unlock(9) 🦋

okay so this one is from the Kernel API Manual and it's literally the "let it go" of rados locks 💅

✨ NAME ✨

ceph_cls_unlock — release rados lock for object 🔓

like, you grabbed the lock, you did your thing, and now bestie you gotta release it. that's the whole job. no cap.

✨ SYNOPSIS ✨

int ceph_cls_unlock (struct ceph_osd_client *osdc , struct
ceph_object_id *oid , struct ceph_object_locator *oloc , char *lock_name
, char *cookie );

it's giving C function signature realness 🎀 it returns an int, and it takes five args — we're gonna go through every single one, don't worry 🫶

✨ ARGUMENTS ✨

• osdc — the OSD client instance 🖥️ your main character, the thing actually doing the talking.
• oid — object to lock 🔒 (yes that's the description, and yes we're keeping it exactly, periodt)
• oloc — object to lock 📍 (and this one's description is also literally "object to lock" — the manpage said what it said, i'm just the messenger 🙈)
• lock_name — the name of the lock 🏷️ gotta know which lock we're unlocking, obviously.
• cookie — user-defined identifier for this instance of the lock 🍪 not a snack!! it's your tag for your particular grab of that lock, and you define it yourself. iykyk.

lowkey important: both oid and oloc are documented as "object to lock" — that's straight from the original page, so don't come for me 😭
