Mateusz Guzik f4fee216df apparmor: try to avoid refing the label in apparmor_file_open ... If the label is not stale (which is the common case), the fact that the passed file object holds a reference can be leverged to avoid the ref/unref cycle. Doing so reduces performance impact of apparmor on parallel open() invocations. When benchmarking on a 24-core vm using will-it-scale's open1_process ("Separate file open"), the results are (ops/s): before: 6092196 after: 8309726 (+36%) Signed-off-by: Mateusz Guzik <mjguzik@gmail.com> Signed-off-by: John Johansen <john.johansen@canonical.com>		2024-07-24 11:05:14 -07:00
