struct dentry *dentry
umode_tmode
void *arg
331  map等于arg
333  返回:bpf_mkobj_ops(dentry, mode, arg, & bpf_map_iops, bpf_map_support_seq_show(map) ? & pffs_map_fops should only implement the basic* read operation for a BPF map. The purpose is to* provide a simple user intuitive way to do* "cat bpffs/pathto/a-pinned-map".* Other operations (e.g. write, lookup...) should be realized by : & bpffs_obj_fops)
