[PATCH 0/2] USB: core: add a way to revoke access to open USB devices

[Bastien Nocera <hadess@hadess.net>]

BPF list, first CC: here, I hope the commit messages are clear enough to
understand the purpose of the patchset. If not, your comments would be
greatly appreciated so I can make the commit messages self-explanatory.

Eric, what would be the right identifier to use for a specific user
namespace that userspace could find out? I know the PIDs of the
bubblewrap processes that created those user namespaces, would those be
good enough?

Changes since v2:
- Changed the internal API to pass a struct usb_device
- Fixed potential busy loop in user-space when revoking access to a
  device
