From aefad9593ec5ad4aae5346253a8b646364cd7317 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 22 Mar 2018 20:52:43 -0500 Subject: sem/security: Pass kern_ipc_perm not sem_array into the sem security hooks All of the implementations of security hooks that take sem_array only access sem_perm the struct kern_ipc_perm member. This means the dependencies of the sem security hooks can be simplified by passing the kern_ipc_perm member of sem_array. Making this change will allow struct sem and struct sem_array to become private to ipc/sem.c. Signed-off-by: "Eric W.
