类型参数名称
const void *salt
const char *name
2014  hash等于Hash courtesy of the R5 hash in reiserfs modulo sign bits (salt)
2015  len等于0
2017  c = (unsigned char) * name
2018  当c循环
2019  len自加
2020  hash等于partial hash update function. Assume roughly 4 bits per character
2021  c等于name[len]
2023  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)
