Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-hotplug@vger.kernel.org In looking at the boot process of a 2.5.64 kernel (with DEBUG defined in drivers/base/hotplug.c), I can see hotplug events for each of my ATA disks as they are added to the "ide" bus in sysfs. So far so good. However, I'd like to be able to receive hotplug events for _all_ block devices, regardless of connection type or anything else. In fact, I'd like to receive hotplug events for all block device _minors_ as well, so when the kernel scans (or receives) partition information that would generate events as well. The event would only have to indicate add/remove, "block", and the DEVPATH to the device node in sysfs. Currently, the "whole disk" block devices appear in /sys/block, but the partitions don't seem to appear anywhere in sysfs. However, it appears that the "block" directory is a sysfs "subsystem", not a class, so no hotplug events are generated when the block subsystem adds/removes devices. How should this be accomplished? Should the "block" subsystem really be a sysfs "class"? ------------------------------------------------------- This SF.net email is sponsored by:Crypto Challenge is now open!
