Subject: [PATCH 1/5] autofs: remove unused AUTOFS_IOC_EXPIRE_DIRECT/INDIRECT
Date: Wed, 16 Aug 2017 10:31:13 +0800
Message-ID: <150285067347.4670.11494624644273072003.stgit@pluto.themaw.net> (raw)

From: Tomohiro Kusumi <tkusumi@tuxera.com>

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
existing ioctl AUTOFS_IOC_EXPIRE_MULTI.

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
