Subject: [PATCH 05/16] elf, uapi: Add type ElfXX_Versym
Date: Mon, 03 Feb 2025 10:05:06 +0100 [thread overview]
Message-ID: <20250203-parse_vdso-nolibc-v1-5-9cb6268d77be@linutronix.de> (raw)
In-Reply-To: <20250203-parse_vdso-nolibc-v1-0-9cb6268d77be@linutronix.de>
The types are used by tools/testing/selftests/vDSO/parse_vdso.c.
To be able to build the vDSO selftests without a libc dependency,
add the types to the kernels own UAPI headers.
As documented by elf(5).
