Chao Yu 04d47e6738 f2fs: fix to account total free nid correctly ... Thread A Thread B Thread C - f2fs_create - f2fs_new_inode - f2fs_lock_op - alloc_nid alloc last nid - f2fs_unlock_op - f2fs_create - f2fs_new_inode - f2fs_lock_op - alloc_nid as node count still not be increased, we will loop in alloc_nid - f2fs_write_node_pages - f2fs_balance_fs_bg - f2fs_sync_fs - write_checkpoint - block_operations - f2fs_lock_all - f2fs_lock_op While creating new inode, we do not allocate and account nid atomically, so that when there is almost no free nids left, we may encounter deadloop like above stack. In order to avoid that, reuse nm_i::available_nids for accounting free nids and make nid allocation and counting being atomical during node creation.
