Subject: [PATCH] vt: remove old FONT ioctls definitions in uapi
Date: Fri, 22 Jul 2022 14:11:33 +0800	[thread overview]
Message-ID: <20220722061133.7765-1-yixingrui@linux.alibaba.com> (raw)

As was demonstrated by commit ff2047fb755d ("vt: drop old FONT ioctls"),
old font ioctls like PIO_FONT have been deleted and KDFONTOP ioctl is used
for years instead.

However, unused definitions of these ioctl numbers and "strut
consolefontdesc" still exist in a uapi header. They could have been removed
since no userspace was using them. Otherwise they will become a
misleading for users, and users will fail with ENOTTY with wrong call.

We are moving old font ioctl numbers definitions here to guide users to
use KDFONTOP.
