[PATCH] Reduce SELinux check on KDSKBENT/SENT ioctls
From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch reduces the full capability check in the SELinux module for the
KDSKBENT/SENT ioctls to only check the corresponding SELinux permission,
avoiding a change to the Linux permissions model for these operations.
