Subject[PATCH 4.14 076/183] block: Set BIO_TRACE_COMPLETION on new bio during split
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Goldwyn Rodrigues <rgoldwyn@suse.com>


[ Upstream commit 20d59023c5ec4426284af492808bcea1f39787ef ]

We inadvertently set it again on the source bio, but we need
to set it on the new split bio instead.

Fixes: fbbaf700e7b1 ("block: trace completion of all bios.")
