[PATCH kernel-4.19 01/32] ascend: sharepool: don't enable the vmalloc to use hugepage default
by Yang Yingliang 08 Mar '21

08 Mar '21

From: Ding Tianhong <dingtianhong(a)huawei.com> ascend inclusion category: feature bugzilla: NA CVE: NA ------------------------------------------------- The commit 59a57a82fb2a ("mm/vmalloc: Hugepage vmalloc mappings") would enable the vmalloc for hugepage default when the alloc size is bigger than the PMD_SIZE, it looks like the transparent hugepage for mmap, the driver could not control the hugepage accurately and be break the logic, now the share pool already export the vmalloc_hugepage_xxx function to control the vmalloc hugepage allocation, it looks like the static hugepage for vmalloc, so disable the transparent hugepage function. This patch also fix the problem of breaking the kabi of vm_struct, the user could applied it for commercial version.
