Subject: [PATCH v3 03/21] x86/insn: Add a __ignore_sync_check__ marker
Date: Thu,  4 Mar 2021 18:42:19 +0100	[thread overview]
Message-ID: <20210304174237.31945-4-bp@alien8.de> (raw)
In-Reply-To: <20210304174237.31945-1-bp@alien8.de>

From: Borislav Petkov <bp@suse.de>

Add an explicit __ignore_sync_check__ marker which will be used to mark
lines which are supposed to be ignored by file synchronization check
scripts, its advantage being that it explicitly denotes such lines in
the code.

Signed-off-by: Borislav Petkov <bp@suse.de>
