Messages in this thread Patch in this message | | | From | Atul Raut <> | Subject | [PATCH] ipc:msg: Replace zero-length arrays with DECLARE_FLEX_ARRAY() helper | Date | Sun, 30 Jul 2023 19:25:57 -0700 |
| |
Replacing zero-length arrays with C99 flexible-array members because they are deprecated. Use the new DECLARE_FLEX_ARRAY() auxiliary macro instead of defining a zero-length array.
This fixes warnings such as: ./ipc/msg.c:981:6-11: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
