drbd: use consistent license DRBD currently has a mix of GPL-2.0 and GPL-2.0-or-later SPDX license identifiers. We have decided to stick with GPL 2.0 only, so consistently use that identifier.

drbd: debugfs: add basic hierarchy Add new debugfs hierarchy /sys/kernel/debug/ drbd/ resources/ $resource_name/connections/peer/$volume_number/ $resource_name/volumes/$volume_number/ minors/$minor_number -> ../resources/$resource_name/volumes/$volume_number/ Followup commits will populate this hierarchy with files containing statistics, diagnostic information and some attribute data.

block: drbd: no need to check return value of debugfs_create functions When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.
