Subject: [PATCH] HID: bpf: Sync KF_SLEEPABLE flags in hid_bpf_syscall_kfuncs set
Date: Fri, 24 Apr 2026 18:22:35 +0800 [thread overview]
Message-ID: <20260424-btf-define-v1-1-0f52dffad5aa@kylinos.cn> (raw)
From: Zhao Mengmeng <zhaomengmeng@kylinos.cn>
Pahole intersects flags across BTF_ID_FLAGS() occurrences, so omitting
KF_SLEEPABLE may drops the flags globally. sync this flags in
hid_bpf_syscall_kfuncs set to enforce consistency and safety.
