| |
3.2.97-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Joerg Roedel <jroedel@suse.de>
commit ce76353f169a6471542d999baf3d29b121dce9c0 upstream.
The function only sends the flush command to the IOMMU(s), but does not wait for its completion when it returns. Fix that.
