Name:find_last_bit
Proto:unsigned long find_last_bit(const unsigned long *addr, unsigned long size)
Type:unsigned long
Parameter:
Type | Parameter | Name |
---|---|---|
const unsigned long * | addr | |
unsigned long | size |
133 | If size Then |
134 | val = BITMAP_LAST_WORD_MASK(size) |
135 | idx = (size - 1) / BITS_PER_LONG |
137 | Do |
139 | If val Then Return idx * BITS_PER_LONG + __fls: find last set bit in word*@word: The word to search* Undefined if no set bit exists, so code should check against 0 first. |
142 | val = ~0ul |
145 | Return size |
