Hi all, I happened to stumble into some (Linux kernel) bug a few days ago and hopefully managed to collect evidences of its cause, bissection for instance. I was really in need to share my report with the Community, but pitifully failed to spot the right mailing lists involved. That's why some of you might consider this message bothersome. For the rest, the people who really care about this bug, please, follow this pointer : https://bugzilla.kernel.org/show_bug.cgi?id=196343 For eager people, offending commit is : commit 82ed4db499b8598f16f8871261bff088d6b0597f Author: Christoph Hellwig <hch@xxxxxx> Date: Fri Jan 27 09:46:29 2017 +0100 block: split scsi_request out of struct request And require all drivers that want to support BLOCK_PC to allocate it as the first thing of their private data. To support this the legacy IDE and BSG code is switched to set cmd_size on their queues to let the block layer allocate the additional space. Signed-off-by: Christoph Hellwig <hch@xxxxxx> Signed-off-by: Jens Axboe <axboe@xxxxxx> And, not as an option, you the specialists, please tell me which the right mailing lists are to post such a bug report. Thanks in advance for any kind of comment.
