Subject: block: Set BIO_TRACE_COMPLETION on new bio during split
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=20d59023c5ec4426284af492808bcea1f39787ef;p=linux.git

block: Set BIO_TRACE_COMPLETION on new bio during split

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.")
