Hi,

Anyone can check whether the below patch is fine?  Basically I just
cast the type accordingly and won't know it is right or not... ...

Fix below warnings with gcc version 4.1.2 20080704 (Red Hat 4.1.2-48):

drivers/xen/blktap/device.c: In function ‘blktap_device_create’:
drivers/xen/blktap/device.c:869: warning: format ‘%llu’ expects type
‘long long unsigned int’, but argument 5 has type ‘sector_t’
drivers/xen/blktap/device.c: In function ‘blktap_device_debug’:
drivers/xen/blktap/device.c:898: warning: format ‘%llu’ expects type
‘long long unsigned int’, but argument 4 has type ‘sector_t’

Patch below:
