Nicholas Bellinger [Tue, 26 Jul 2011 07:38:40 +0000 (00:38 -0700)]
This patch adds the new macro usage of include/linux/kernel.h:DIV_ROUND_UP_SECTOR_T
for the new DIV_ROUND_UP_ULL() usage for 32-bit architectures with unsigned long long
sector_t division in transport_allocate_data_tasks() usage for target_core_mod v4.1
