Subject: perf symbols: Introduce symbol__elf_init()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=166ccc9c244828da9214a0e7ba4d5dde6a26dcc1;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

perf symbols: Introduce symbol__elf_init()

The symbol__elf_init() is for initializing internal libelf data
structure and getting rid of its dependency outside of ELF/symboling
handling code.
