    Subject[PATCH AUTOSEL 5.8 14/62] gcc-plugins/stackleak: Don't instrument itself
    Date
    From: Alexander Popov <alex.popov@linux.com>

    [ Upstream commit 005e696df65d0ff90468ecf38a50aa584dc82421 ]

    There is no need to try instrumenting functions in kernel/stackleak.c.
    Otherwise that can cause issues if the cleanup pass of stackleak gcc plugin
    is disabled.
