[PATCH] fio: consolidate rand_seed to uint64_t

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



csscope showed rand_seed was defined 4 times - each a different type.
While they are used differently, the places where they overlap
should reference the same type. This patch makes three of them the same
as suggested by Jens Axboe.
