Revision c8e8c77b3bdbade6e26e8e76595f141ede12b692 authored by Jaesoo Lee on 03 June 2019, 23:42:28 UTC, committed by Sagi Grimberg on 06 June 2019, 16:53:07 UTC
The Number of Namespaces (nn) field in the identify controller data structure is defined as u32 and the maximum allowed value in NVMe specification is 0xFFFFFFFEUL. This change fixes the possible overflow of the DIV_ROUND_UP() operation used in nvme_scan_ns_list() by casting the nn to u64.
