Name:map_fold - fold larger bitmap into smaller, modulo specified size*@dst: resulting smaller bitmap*@orig: original larger bitmap*@sz: specified size*@nbits: number of bits in each of these bitmaps

Proto:void bitmap_fold(unsigned long *dst, const unsigned long *orig, unsigned int sz, unsigned int nbits)

Type:void

Parameter:

1011  If dst == orig Then Return
1013  bitmap_zero(dst, nbits)
1015  for_each_set_bit(oldbit, orig, nbits)
1016  set_bit - Atomically set a bit in memory*@nr: the bit to set*@addr: the address to start counting from* This is a relaxed atomic operation (no implied memory barriers).* Note that @nr may be almost arbitrarily large; this function is not
