Code creates a local version of the variable that exists in the larger
block.
Example #1: from Linux-2.6-rc3 file
lib/crc32.c
184 u32 __attribute_pure__ crc32_be(u32 crc,
unsigned char const *p, size_t len)
185 {
186 - 199 ....
200
u8 *p = (u8 *)b;
Local variable p at line 200 creates a local variable p that masks the
one passed to the function.
Example #2: from Linux-2.6-rc3
drivers/scsi/aic7xxx/aic79xx_pci.c
285
struct scb_data *shared_scb_data;
286
u_int
command;
287
uint32_t devconfig;
288
uint16_t subvendor;
289
int
error;
290 - 326 ....
327
if ((ahd->flags & (AHD_39BIT_ADDRESSING|AHD_64BIT_ADDRESSING))
! = 0) {
328
uint32_t devconfig;
How to resolve:
Renaming variable in internal scope is
most likely course of action. Caution must be taken to make sure
this doesn't cause problems with the code.
