Subject: [RFC PATCH v1 13/14] bpf: Make bpf_throw available to all program types
Date: Thu,  1 Feb 2024 04:21:08 +0000	[thread overview]
Message-ID: <20240201042109.1150490-14-memxor@gmail.com> (raw)
In-Reply-To: <20240201042109.1150490-1-memxor@gmail.com>

Move bpf_throw kfunc to common_kfunc_set so that any program type can
utilize it to throw exceptions. This will also be useful to test a wider
variety of programs to test the cleanup logic properly.
