From 89dd9bb25597621ca0500aa598140ff0858091e2 Mon Sep 17 00:00:00 2001 From: Yiming Xiang Date: Wed, 28 Aug 2024 23:17:12 -0400 Subject: [PATCH] docs/bpf: Fix a typo in verifier.rst In verifier.rst, there is a typo in section 'Register parentage chains'. Caller saved registers are r0-r5, callee saved registers are r6-r9. Here by context it means callee saved registers rather than caller saved registers. This may confuse users.
