[PATCH 0/3] drivers: support for sysfs initiated coredump

This series is intended for 4.17 adding support for sysfs initiated coredump. This uses new functionality that was added in drivers base. Device drivers can now implement a .coredump() callback upon which a sysfs entry is created when the device is bound to the driver. From user-space a device core

[PATCH 3/3] btmrvl: support sysfs initiated firmware coredump
