From 685dadafbde29dc3d6b7a13be284d684b06d4d4f Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Fri, 15 Mar 2024 15:44:44 +0100 Subject: [PATCH] HID: bpf: allow to use bpf_timer_set_sleepable_cb() in tracing callbacks. Export the sleepable kfuncs we have on HID-BPF in tracing bpf programs, but with the condition of being used in a sleepable context. This allows to use the bpf_timer when used in a sleepable context through bpf_timer_set_sleepable_cb() and initiate work from a device event.
