Subject: osd: Set the from shard in the EC read reply.
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=332b547ff8eb86fda076f098c2d3b740d67c4e2f;p=ceph.git

osd: Set the from shard in the EC read reply.

This was not necessary prior to direct reads, but is essential when the
client needs to know which shard the read came from.
