Subject: [PATCH 13/35] UAPI: elf_read_implies_exec() is a kernel-only feature - so hide from userspace
Date: Sat, 02 Jul 2011 12:09:27 +0100 [thread overview]
Message-ID: <20110702110927.21948.8187.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <20110702110716.21948.74214.stgit@warthog.procyon.org.uk>
elf_read_implies_exec() is a kernel-only feature as the second parameter is a
constant that isn't exported to userspace. Not only that, but the
arch-specific overrides are not exported either.
So hide the macro from userspace.
Similarly, struct file should not be predeclared in userspace.
