[Xen-devel] [BLKTAP]: Kill duplicate fast_flush_area call
Hi Keir:
[BLKTAP]: Kill duplicate fast_flush_area call
The dispatch_rw_block_io may call fast_flush_area twice if
create_lookup_pte_addr fails (there is a flush call at fail_flush
already). The second call simply causes warnings to be printed
on the console. This patch removes the duplicate call.
