[ceph-users] which exact decimal value is meant here for S64_MIN in CRUSH Mapper

Hi, In *mapper.c* file of Ceph CRUSH, I am trying to understand the definition of a linux macro ```*S64_MIN*``` used in the following ```*else*``` condition i.e. ```*draw = S64_MIN*```. Which exact decimal value is meant here for ```*S64_MIN*```? ``` if (weights[i]) { u = hash(bucket->h.hash, x, ids[i], r); u &= 0xffff; ln = crush_ln(u) - 0x1000000000000ll; __s64 draw = div64_s64(ln, weights[i]); } else { __s64 draw = S64_MIN; // #define S64_MAX ((s64)(U64_MAX >> 1)) // #define S64_MIN ((s64)(-S64_MAX -1)) } if (i == 0 || draw > high_draw) { high = i; high_draw = draw; } } return bucket->h.items[high]; } Thanks Bobby !
