Name:get_symbol_pos
Proto:static unsigned long get_symbol_pos(unsigned long addr, unsigned long *symbolsize, unsigned long *offset)
Type:unsigned long
Parameter:
Type | Parameter | Name |
---|---|---|
unsigned long | addr | |
unsigned long * | symbolsize | |
unsigned long * | offset |
202 | symbol_start = 0 , symbol_end = 0 |
208 | Else BUG_ON(!kallsyms_offsets) |
212 | low = 0 |
213 | high = Tell the compiler that the count isn't in the small data section if the arch* has one (eg: FRV). |
217 | If kallsyms_sym_address(mid) <= addr Then low = mid |
227 | When low && kallsyms_sym_address(low - 1) == kallsyms_sym_address(low) cycle |
228 | --low |
230 | symbol_start = kallsyms_sym_address(low) |
234 | If kallsyms_sym_address(i) > symbol_start Then |
235 | symbol_end = kallsyms_sym_address(i) |
236 | Break |
241 | If Not symbol_end Then |
242 | If is_kernel_inittext(addr) Then symbol_end = _einittext |
250 | If symbolsize Then symbolsize = symbol_end - symbol_start |
252 | If offset Then offset = addr - symbol_start |
255 | Return low |

kallsyms_lookup_size_offset | Lookup an address but don't bother to find any names. |
kallsyms_lookup | Lookup an address* - modname is set to NULL if it's in the kernel.* - We guarantee that the returned name is valid until we reschedule even if.* It resides in a module.* - We also guarantee that modname will be valid until rescheduled. |
