From a25ecd9d1e60241df905b29fb84765eb74545c4f Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 18 Nov 2019 11:40:59 +0000 Subject: [PATCH] bpf: Fix memory leak on object 'data' The error return path on when bpf_fentry_test* tests fail does not kfree 'data'. Fix this by adding the missing kfree.
