Messages in this thread Patch in this message | | | From | Alaa Mohamed <> | Subject | [PATCH v2] intel: igb: igb_ethtool.c: Convert kmap() to kmap_local_page() | Date | Sat, 16 Apr 2022 03:19:20 +0200 |
| |
The use of kmap() is being deprecated in favor of kmap_local_page() where it is feasible.
With kmap_local_page(), the mapping is per thread, CPU local and not globally visible.
