From: Mike Rapoport <rppt@xxxxxxxxxxxxx> There are a couple of kernel-doc comments in include/linux/mmzone.h but they have minor formatting issues that would cause kernel-doc warnings. Fix the formatting of those comments, add missing Return: descriptions and link include/linux/mmzone.h to Documentation/core-api/mm-api.rst Signed-off-by: Mike Rapoport <rppt@xxxxxxxxxxxxx> Reviewed-by: Matthew Wilcox (Oracle) <willy@xxxxxxxxxxxxx> Reviewed-by: Anshuman Khandual <anshuman.khandual@xxxxxxx> --- Documentation/core-api/mm-api.rst | 1 + include/linux/mmzone.h | 43 +++++++++++++++++-------------- 2 files changed, 25 insertions(+), 19 deletions(-) diff --git a/Documentation/core-api/mm-api.rst b/Documentation/core-api/mm-api.rst index 34f46df91a8b..a42f9baddfbf 100644 --- a/Documentation/core-api/mm-api.rst +++ b/Documentation/core-api/mm-api.rst @@ -97,3 +97,4 @@ More Memory Management Functions :internal: .. kernel-doc:: include/linux/mm.h :internal: +.. kernel-doc:: include/linux/mmzone.h diff --git a/include/linux/mmzone.h b/include/linux/mmzone.h index 965a0cd5eac1..0d53eba1c383 100644 --- a/include/linux/mmzone.h +++ b/include/linux/mmzone.h @@ -1007,7 +1007,8 @@ static inline int is_highmem_idx(enum zone_type idx) * is_highmem - helper function to quickly check if a struct zone is a * highmem zone or not.
