| Subject: mm/damon/dbgfs: use kmalloc for allocating only one element |
| Date: Mon, 8 Aug 2022 15:00:19 -0700 |
| |
| Use kmalloc(...) rather than kmalloc_array(1, ...) because the number of |
| elements we are specifying in this case is 1, kmalloc would accomplish the |
| same thing and we can simplify. |
