This leads to crashes\nlike the following:\n\n\t============================================\n\tWARNING: possible recursive locking detected\n\t6.18.0-mainline-maybe-dirty #1 Tainted: G          IO\n\t--------------------------------------------\n\tkswapd0/68 is trying to acquire lock:\n\tffff956000fa18b0 (&l->lock){+.+.}-{2:2}, at: lock_list_lru_of_memcg+0x128/0x230\n\n\tbut task is already holding lock:\n\tffff956000fa18b0 (&l->lock){+.+.}-{2:2}, at: rust_helper_spin_lock+0xd/0x20\n\n\tother info that might help us debug this:\n\t Possible unsafe locking scenario:\n\n\t       CPU0\n\t       ----\n\t  lock(&l->lock);\n\t  lock(&l->lock);\n\n\t *** DEADLOCK ***\n\n\t May be due to missing lock nesting notation\n\n\t3 locks held by kswapd0/68:\n\t #0: ffffffff90d2e260 (fs_reclaim){+.+.}-{0:0}, at: kswapd+0x597/0x1160\n\t #1: ffff956000fa18b0 (&l->lock){+.+.}-{2:2}, at: rust_helper_spin_lock+0xd/0x20\n\t #2: ffffffff90cf3680 (rcu_read_lock){....}-{1:2}, at: lock_list_lru_of_memcg+0x2d/0x230\n\nTo fix this, remove the spin_lock() call from rust_shrink_free_page().",
