| Subject: mm: cma: print cma name as well in cma_alloc debug |
| Date: Fri, 7 Jul 2023 00:03:34 +0530 |
| |
| CMA allocation can happen either from global cma or from dedicated cma |
| region. |
| |
| Thus it is helpful to print cma name as well during initial |
| debugging to confirm cma regions were getting initialized or not. |
