Subject: [PATCH 1/5] autofs: remove unused AUTOFS_IOC_EXPIRE_DIRECT/INDIRECT
Date: Wed, 16 Aug 2017 10:31:13 +0800	[thread overview]
Message-ID: <> (raw)

From: Tomohiro Kusumi <>

These are not used by either kernel or userspace, although
AUTOFS_IOC_EXPIRE_DIRECT once seems to have been used by userspace
in around 2006-2008, which was technically just an alias of the

ioctls for autofs are already complicated enough that they could
be removed unless these are staying here to be able to compile
userspace code of certain period of time from a decade ago.

Edit: imk
Yes, this is indeed very old and anything that still uses must
be updated becuase it will be using broken functionality.
End edit: imk
