✨ SYNOPSIS ✨

int xe_vm_lock (struct xe_vm *vm , bool intr );

🎀 ARGUMENTS 🎀

• vm — The struct xe_vm whose lock is to be locked. like, this is the vm we're locking, no cap. 🔒
• intr — Whether to perform any wait interruptible. so this bool decides if the wait can get interrupted. 🦋

• 0 on success. slay. ✨
• -EINTR if intr is true and the wait for a contended lock was interrupted. 😭
• If intr is false, the function always returns 0. periodt. 💅
