Subject: [PATCH v4 0/2] mm: add vmalloc_no_huge and use it
Date: Mon, 14 Jun 2021 15:23:55 +0200 [thread overview]
Message-ID: <20210614132357.10202-1-imbrenda@linux.ibm.com> (raw)
Add vmalloc_no_huge and export it, so modules can allocate memory with
small pages.
Use the newly added vmalloc_no_huge in KVM on s390 to get around a
hardware limitation.
v3->v4:
* reword commit messages to be more clear
* add comment in the second patch
v2->v3:
* do not export __vmalloc_node_range
* add vmalloc_no_huge as a wrapper around __vmalloc_node_range
* use vmalloc_no_huge instead of __vmalloc_node_range in kvm on s390x
