Very similar to VM_WARN_ON_ONCE_PAGE and VM_BUG_ON_PAGE, add VM_WARN_ON_PAGE macro. Signed-off-by: Muchun Song <redacted> --- include/linux/mmdebug.h | 8 ++++++++ 1 file changed, 8 insertions(+)I was going to question the use/need for this macro in the following patch. Looks like Oscar has already done that, and free_bootmem_page will now use VM_BUG_ON_PAGE. So, this patch can be dropped.
In the previous version, Oscar suggested I use WARN_ON instead of BUG_ON. But he realised we actually should use BUG_ON in this version. So I will drop this in the next version. Thanks.
