From 1a530a6f23f7dca336311ef60c9ca26f3dc63688 Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 22 Mar 2011 16:34:48 -0700 Subject: binfmt_elf: quiet GCC-4.6 'set but not used' warning in load_elf_binary() With GCC-4.6 we get warnings about things being 'set but not used'. In load_elf_binary() this can happen with reloc_func_desc if ELF_PLAT_INIT is defined, but doesn't use the reloc_func_desc argument. Quiet the warning/error by marking reloc_func_desc as __maybe_unused.

Moreover, dropping the dependency on task_struct will help make both existing and future operations on mm's more flexible and convenient.
