Subject: [for-next][PATCH 17/20] ftrace: Remove obsoleted code from ftrace and task_struct
Date: Tue, 27 Sep 2022 12:02:33 -0400 [thread overview]
Message-ID: <20220927160250.439945082@goodmis.org> (raw)
In-Reply-To: 20220927160216.349640304@goodmis.org
From: Gaosheng Cui <cuigaosheng1@huawei.com>
The trace of "struct task_struct" was no longer used since
commit 345ddcc882d8 ("ftrace: Have set_ftrace_pid use the
bitmap like events do"), and the functions about flags for
current->trace is useless, so remove them.
