From 05a248715cef192336a594afed812871a52efc1f Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 21 Dec 2021 16:20:32 +0100 Subject: user: move common-user includes to a subdirectory of {bsd,linux}-user/ Avoid polluting the compilation of common-user/ with local include files; making an include file available to common-user/ should be a deliberate decision in order to keep a clear interface that can be used by both bsd-user/ and linux-user/.
