My feedback about the pscsi_get_blocks() was misleading: what I meant is
that it is not necessary to introduce RCU locking in that function. I
think that using bdev_nr_sects() or part_nr_sects_read() to read
nr_sects in that function is useful.
Is there any reason that the following Xen macro has not been converted?
#define vbd_sz(_v) ((_v)->bdev->bd_part ? \
(_v)->bdev->bd_part->nr_sects : \
get_capacity((_v)->bdev->bd_disk))
Thanks,
Bart.
