Subject: [PATCH bpf-next] bpf: preserve sleepable bit in subprog info
Date: Wed, 13 Mar 2024 17:01:27 -0700 [thread overview]
Message-ID: <20240314000127.3881569-1-andrii@kernel.org> (raw)
Copy over main program's sleepable bit into subprog's info. This might
be important for, e.g., freplace cases.
