Name:Determine if an address is within the vmalloc range* On nommu, vmalloc/vfree wrap through kmalloc/kfree directly, so there* is no special casing required.

Proto:static inline bool is_vmalloc_addr(const void *x)

Type:bool

Parameter:

TypeParameterName
const void *x
631  addr = x
633  Return addr >= VMALLOC_START && addr < VMALLOC_END

kvfreekvfree() - Free memory.*@addr: Pointer to allocated memory.* kvfree frees memory allocated by any of vmalloc(), kmalloc() or kvmalloc().* It is slightly more efficient to use kfree() or vfree() if you are certain* that you know which one to use.
per_cpu_ptr_to_physper_cpu_ptr_to_phys - convert translated percpu address to physical address*@addr: the address to be converted to physical address* Given @addr which is dereferenceable address obtained via one of* percpu access macros, this function translates it into
is_vmalloc_or_module_addr
s_show
bio_map_kern_map_kern - map kernel address into bio*@q: the struct request_queue for the bio*@data: pointer to buffer to map*@len: length in bytes*@gfp_mask: allocation flags for bio allocation* Map the kernel address into a bio suitable for io to a block* device
unpack_tablepack_table - unpack a dfa table (one of accept, default, base, next check)*@blob: data to unpack (NOT NULL)*@bsize: size of blob* Returns: pointer to table else NULL on failure* NOTE: must be freed by kvfree (not kfree)
