Subject: [RFC PATCH 0/6] hv_sock: Hardening changes
Date: Wed, 13 Apr 2022 22:47:36 +0200	[thread overview]
Message-ID: <20220413204742.5539-1-parri.andrea@gmail.com> (raw)

Miscellaneous changes to "harden" the hv_sock driver and enable it
in isolated guests.  The diff in ring_buffer.c, hyperv.h is due to
a consequent refactoring/code elimination (patch #6).

Applies to v5.18-rc2.

Thanks,
  Andrea
