[PATCH 0/7] rbd: implement single-major device number allocation scheme

at once. See individual commit messages for details. Fixes: http://tracker.ceph.com/issues/5048 Thanks, Ilya Ilya Dryomov (7): rbd: rbd_device::dev_id is an int, format it as such rbd: tweak loaded message and module description rbd: refactor rbd_init() a bit rbd: switch

[PATCH 2/7] rbd: tweak loaded message and module description

Tweak loaded message, so that it looks like [ 30.184235] rbd: loaded instead of [ 38.056564] rbd: loaded rbd (rados block device) Also move (and slightly tweak) MODULE_DESCRIPTION so that all authors are next to each other in modinfo output. Signed-off-by: Ilya Dryomov ilya.dryo

[PATCH 5/7] rbd: add 'minor' sysfs rbd device attribute

Introduce /sys/bus/rbd/devices/id/minor sysfs attribute for exporting rbd whole disk minor numbers. This is a step towards single-major device number allocation scheme, but also a good thing on its own. Signed-off-by: Ilya Dryomov ilya.dryo...@inktank.com Reviewed-by: Alex Elder el...@linaro.org

[PATCH 4/7] rbd: switch to ida for rbd id assignments

completely unpredictable. So, in preparation for single-major device number allocation scheme, which is going to establish and rely on a constant mapping between rbd ids and device numbers, switch to ida for rbd id assignments.

[PATCH 6/7] rbd: wire up is_visible() sysfs callback for rbd bus

In preparation for single-major device number allocation scheme, wire up attribute_group::is_visible() callback for rbd bus. This allows us to make the new single-major attributes conditional. Signed-off-by: Ilya Dryomov ilya.dryo...@inktank.com Reviewed-by: Alex Elder el...@linaro.org Reviewed
