With the current workflow of adding these groups with a separate call to sysfs after the device has been created we are introducing a race with udev, as the uevent is generated before the sysfs attributes are created, and udev fails to read the required information. This patchset adds a new function 'device_add_disk_with_groups()' and converts the obvious candidates to use this new function. As usual, comments and reviews are welcome. Hannes Reinecke (5): genhd: drop 'bool' argument from __device_add_disk() block: genhd: add device_add_disk_with_groups nvme: register ns_id attributes as default sysfs groups aoe: use device_add_disk_with_groups() zram: use device_add_disk_with_groups() block/genhd.c | 38 ++++++++++++++++++++++++++++++-------- drivers/block/aoe/aoe.h | 1 - drivers/block/aoe/aoeblk.c | 21 +++++++-------------- drivers/block/aoe/aoedev.c | 1 - drivers/block/zram/zram_drv.c | 28 +++++++--------------------- drivers/nvme/host/core.c | 14 +++++++------- drivers/nvme/host/multipath.c | 12 +++--------- drivers/nvme/host/nvme.h | 2 +- include/linux/genhd.h | 3 +++ 9 files changed, 58 insertions(+), 62 deletions(-) -- 2.12.3
