[PATCH bpf-next v4 17/25] rqspinlock: Add entry to Makefile, MAINTAINERS
From: Kumar Kartikeya Dwivedi <memxor@gmail.com>
Date: 2025-03-16 04:06:07
Also in:
bpf, lkml
Subsystem:
bpf [general] (safe dynamic programs and tools), generic include/asm header files, the rest · Maintainers:
Alexei Starovoitov, Daniel Borkmann, Andrii Nakryiko, Eduard Zingerman, Kumar Kartikeya Dwivedi, Arnd Bergmann, Linus Torvalds
Ensure that the rqspinlock code is only built when the BPF subsystem is compiled in. Depending on queued spinlock support, we may or may not end up building the queued spinlock slowpath, and instead fallback to the test-and-set implementation. Also add entries to MAINTAINERS file.
