stable inclusion from stable-v6.6.33 commit 775de4e954cbafd939ce07735b10c9e7fd56a8ea category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 2fd3ef1b9265eda7f53b9506f1ebfb67eb6435a2 upstream.
Since the dynevent/add_remove_btfarg.tc test case forgets to ensure that fprobe is enabled for some structure field access tests which uses the fprobe, it fails if CONFIG_FPROBE=n or CONFIG_FPROBE_EVENTS=n. Fixes it to ensure the fprobe events are supported.
