| 2022-11-08 | mm: vmalloc: add alloc_vmap_area trace event | Uladzislau Rezki (Sony) | 1 | -0/+56 | |
| Patch series "Add basic trace events for vmap/vmalloc (v2)", v2. This small series add some basic trace events for the vmap/vmalloc code. Since currently we lack any, sometimes it is hard to start debuging vmap code if an issue is reported or occured. For example https://lore.kernel.org/linux-mm/Y0p8BZIiDXLQbde%2F@pc636/T/ The final patch adds two reviewers for vmalloc code. This patch (of 7): It is for debug purposes and for validation of passed parameters.
