.SH "DESCRIPTION"
.PP
Undo the effects of
\fBsysfs_break_active_protection\fR\&. Since this function calls
\fBkernfs_put\fR
on the kernfs node that corresponds to the \*(Aqattr\*(Aq argument passed to
\fBsysfs_break_active_protection\fR
that attribute may have been removed between the
\fBsysfs_break_active_protection\fR
and
\fBsysfs_unbreak_active_protection\fR
calls, it is not safe to access
\fIkn\fR
after this function has returned\&.
