Messages in this thread Patch in this message | | | From | Rasmus Villemoes <> | Subject | [PATCH 02/10] linux/net.h: use unique identifier for each struct _ddebug | Date | Tue, 9 Apr 2019 23:25:09 +0200 |
| |
Changes on x86-64 later in this series require that all struct _ddebug descriptors in a translation unit uses distinct identifiers. Realize that for net_dbg_ratelimited by generating such an identifier via __UNIQUE_ID and pass that to an extra level of macros.
No functional change.
