[PATCH] SELinux: cleanup ipc_has_perm
This patch removes the sclass argument from ipc_has_perm in the SELinux
module, as it can be obtained from the ipc security structure. The use of
a separate argument was a legacy of the older precondition function
handling in SELinux and is obsolete. Please apply.
