4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jia Zhu <zhujia13@xxxxxxxxxx>
commit 73c0a9272a7d2942bcae29d4829bf63277cc57c8 upstream.
Previously, we allocated a new block address for OPU mode in direct_IO.
But the new address couldn't be assigned to @map->m_pblk correctly.
This patch fix it.
