[PATCH v2 0/2] Fix a regression with hugetlbfs for shared memory in CoCo VMs

Posted by Chenyi Qiang 3 weeks, 1 day ago

In CoCo VMs, although the hugepage for private memory is not supported yet, Users
can still specify hugetlbfs backend for shared memory. However, due to the
recent changes of ram-block-attributes, it triggers an assertion failure when
getting the block size because the page size of ram_block is different from the
host page size. This patch series fixes this regression and clean up the code to
unify the retrieval of block size.

Chenyi Qiang (2):
  ram-block-attributes: Avoid the overkill of shared memory with
    hugetlbfs backend
  ram-block-attributes: Unify the retrieval of the block size
