Subject: [PATCH bpf-next v1 6/8] HID: bpf: Make syscall kfunc flags match the struct_ops set
Date: Wed, 22 Jul 2026 16:35:16 -0700 [thread overview]
Message-ID: <20260722233518.778854-7-ihor.solodrai@linux.dev> (raw)
In-Reply-To: <20260722233518.778854-1-ihor.solodrai@linux.dev>
Update kfunc flags for hid_bpf_syscall_kfunc_ids set to exactly match
hid_bpf_kfunc_ids set by adding KF_SLEEPABLE flag.
The syscall set omitted the flag because syscall programs are always
sleepable (the verifier rejects a non-sleepable syscall program).
However the upcoming resolve_btfids change enforces per-kfunc flag
consistency across BTF ID sets at build time, which is why this change
is necessary.
