const void *salt
const char *name
2033  hash等于Hash courtesy of the R5 hash in reiserfs modulo sign bits (salt)
2034  len等于0
2036  c = (unsigned char) * name
2037  循环
2038  len自加
2039  hash等于partial hash update function. Assume roughly 4 bits per character
2040  c等于name[len]
2041  当c且c不等于'/'循环
2042  返回:hashlen_create(Finally: cut down the number of bits to a int value (and try to avoid* losing bits). This also has the property (wanted by the dcache)* that the msbits make a good hash table index., len)
