| Series | [blktests,1/2] nvme: enable buffered_io for file-backed namespaces | expand |
Thanks for the test, I actually have a patch for this one, if Christoph and Sagi okay with that I can work on it. Although, not sure if we want that sort of management code in the target. From: linux-block-owner@vger.kernel.org <linux-block-owner@vger.kernel.org> on behalf of Johannes Thumshirn <jthumshirn@suse.de> Sent: Thursday, January 17, 2019 4:59 AM To: Omar Sandoval Cc: Linux Block Layer Mailinglist; Linux NVMe Mailinglist; Anthony Iliopoulos; Johannes Thumshirn Subject: [PATCH blktests 2/2] nvme: test resize of a namespace with file-backed ns Test resizing of a NVMe namespace by creating a file backed namespace over nvme-loop with 1G size, connecting to it and then resizing it to 2G. Check if /proc/partitions and blkdev --getsz $DEVICE see the updated size.
