From: Thomas Weißschuh Date: Mon, 5 Aug 2024 09:39:36 +0000 (+0200) Subject: bpf: Constify ctl_table argument of filter function X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=57e3707eb5e3d9a45eef9151f0378313b1d39a17;p=users%2Fjedix%2Flinux-maple.git bpf: Constify ctl_table argument of filter function The sysctl core is moving to allow "struct ctl_table" in read-only memory. As a preparation for that all functions handling "struct ctl_table" need to be able to work with "const struct ctl_table". As __cgroup_bpf_run_filter_sysctl() does not modify its table, it can be adapted trivially.
