Newer glibc needs to have all variables be size_t even those which are computed into other variables.

[hariharan-devarajan]

Description

In the newer version of glibc this is a compile-time error.

client_read.c:697:30: error: argument 1 range [18446744071562067968, 18446744073709551614] exceeds maximum object size 9223372036854775807 [-Werror=alloc-size-larger-than=]
         reqs = (read_req_t*) calloc(reqs_size, sizeof(read_req_t));

The solution is to change the signature of process_gfid_reads to use size_t in_count.
