Josh Poimboeuf 4ed9d82bf5 objtool: Speed up SHT_GROUP reindexing ... After elf_update_group_sh_info() was introduced, a prototype version of "objtool klp diff" went from taking ~1s to several minutes, due to looping almost endlessly in elf_update_group_sh_info() while creating thousands of local symbols in a file with thousands of sections. Dramatically improve the performance by marking all symbols' correlated SHT_GROUP sections while reading the object. That way there's no need to search for it every time a symbol gets reindexed.
