Revision 0e5e098ac22dae38f957e951b70d3cf73beff0f7 authored by Jan Beulich on 11 March 2013, 09:39:55 UTC, committed by Konrad Rzeszutek Wilk on 18 March 2013, 20:31:22 UTC
Commit 7708992 ("xen/blkback: Seperate the bio allocation and the bio
submission") consolidated the pendcnt updates to just a single write,
neglecting the fact that the error path relied on it getting set to 1
up front (such that the decrement in __end_block_io_op() would actually
drop the count to zero, triggering the necessary cleanup actions).

Also remove a misleading and a stale (after said commit) comment.
