From 69369a7003735d0d8ef22097e27a55a8bad9557a Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Thu, 3 Apr 2014 14:48:27 -0700 Subject: fs, kernel: permit disabling the uselib syscall uselib hasn't been used since libc5; glibc does not use it. Support turning it off. When disabled, also omit the load_elf_library implementation from binfmt_elf.c, which only uselib invokes. bloat-o-meter: add/remove: 0/4 grow/shrink: 0/1 up/down: 0/-785 (-785) function old new delta padzero 39 36 -3 uselib_flags 20 - -20 sys_uselib 168 - -168 SyS_uselib 168 - -168 load_elf_library 426 - -426 The new CONFIG_USELIB defaults to `y'.
