Name:s_power_of_2() - check if a value is a power of two*@n: the value to check* Determine whether some value is a power of two, where zero is* *not* considered a power of two.* Return: true if @n is a power of 2, otherwise false.
Proto:static inline __attribute__((const)) bool is_power_of_2(unsigned long n)

| reg_set_min_max | Adjusts the register min/max values in the case that the dst_reg is the* variable register that we are working on, and src_reg is a constant or we're* simply doing a BPF_K check.* In JEQ/JNE cases we also adjust the var_off values. | 
| reg_set_min_max_inv | Same as above, but for the case that dst_reg holds a constant and src_reg is* the variable reg. | 
| array_map_gen_lookup | mit BPF instructions equivalent to C code of array_map_lookup_elem() |

| alloc_vmap_area | Allocate a region of KVA of the specified size and alignment, within the* vstart and vend. | 
| __do_kmalloc_node | End of slob allocator proper. Begin kmem_cache_alloc and kmalloc frontend. | 
| cma_declare_contiguous | ma_declare_contiguous() - reserve custom contiguous area*@base: Base address of the reserved area optional, use 0 for any*@size: Size of the reserved area (in bytes),*@limit: End address of the reserved memory (optional, 0 for any) | 
| blk_queue_chunk_sectors | set size of the chunk for this queue | 
| blk_revalidate_zone_cb | Helper function to check the validity of zones of a zoned block device. | 
| flags_to_propagation_type | Sanity check the flags to change_mnt_propagation. |

| fsverity_check_hash_algs | |
| fsverity_init_merkle_tree_params | sverity_init_merkle_tree_params() - initialize Merkle tree parameters*@params: the parameters struct to initialize*@inode: the inode for which the Merkle tree is being built*@hash_algorithm: number of hash algorithm to use*@log_blocksize: log base 2 of |
