Subject: [PATCH AUTOSEL 6.1 34/34] tracing: Fix wrong return in kprobe_event_gen_test.c
Date: Wed, 22 Mar 2023 15:59:26 -0400 [thread overview]
Message-ID: <20230322195926.1996699-34-sashal@kernel.org> (raw)
In-Reply-To: <20230322195926.1996699-1-sashal@kernel.org>
From: Anton Gusev <aagusev@ispras.ru>
[ Upstream commit bc4f359b3b607daac0290d0038561237a86b38cb ]
Overwriting the error code with the deletion result may cause the
function to return 0 despite encountering an error. Commit b111545d26c0
("tracing: Remove the useless value assignment in
test_create_synth_event()") solves a similar issue by
returning the original error code, so this patch does the same.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
