Return regs

**Caller**
Name	Describe
check_map_access_type
__check_map_access	heck read/write into map element returned by bpf_map_lookup_elem()
__check_packet_access
check_packet_access
check_sock_access
reg_state
check_mem_access	heck whether memory at (regno + off) is accessible for t = (read \| write)* if t==write, value_regno is a register which value is stored into memory* if t==read, value_regno is a register which will receive the value from memory* if t==write &&
check_helper_mem_access
process_spin_lock	Implementation details:* bpf_map_lookup returns PTR_TO_MAP_VALUE_OR_NULL* Two bpf_map_lookups (even with the same key) will have different reg->id
check_func_arg
record_func_key
check_helper_call
adjust_scalar_min_max_vals	WARNING: This function does calculations on 64-bit values, but the actual* execution may occur on 32-bit values. Therefore, things like bitshifts* need extra checks in the 32-bit case.
check_alu_op	heck validity of 32-bit and 64-bit arithmetic operations
check_ld_imm	verify BPF_LD_IMM64 instruction
check_ld_abs	verify safety of LD_ABS\|LD_IND instructions:* - they can only appear in the programs where ctx == skb* - since they are wrappers of function calls, they scratch R1-R5 registers,* preserve R6-R9, and store return value into R0* Implicit input:* ctx == skb
