Date: Sat, 2 May 2015 19:59:39 +0300 From: Oded Gabbay <oded.gabbay@....com> To: Joerg Roedel <joro@...tes.org>, Linus Torvalds <torvalds@...ux-foundation.org> CC: <linux-kernel@...r.kernel.org>, <iommu@...ts.linux-foundation.org> Subject: Re: [git pull] IOMMU Updates for Linux v4.1 Hello Linus, I've been trying for almost 3 weeks to get the patch at http://lists.linuxfoundation.org/pipermail/iommu/2015-April/012757.html into the IOMMU tree. However, Joerg is not answering my emails for some reason (vacation/sick?) This is a small patch to amd_iommu_v2.c, but it fixes a *big* bug, which causes a kernel thread to be stuck and resources to not be freed. As amdkfd (AMD HSA kernel driver) is the only client for amd_iommu_v2 driver, it effects only HSA systems. I would like to get this into 4.1 and I also marked it as stable for 4.0. Could you please take a look, ack it and pull it to -rc3/4 ? I can send you the patch again with git or I can also send it through Dave's drm pull request if that's more convenient for you.
