From 894e48cada64ec384873fad4fe1b0d0c7de31a29 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 22 Apr 2020 12:32:03 +0200 Subject: objtool: Constify 'struct elf *' parameters In preparation to parallelize certain parts of objtool, map out which uses of various data structures are read-only vs. read-write. As a first step constify 'struct elf' pointer passing, most of the secondary uses of it in find_symbol_*() methods are read-only. Also, while at it, better group the 'struct elf' handling methods in elf.h.
