Hugepages can be specified to pernode since "hugetlbfs: extend the
definition of hugepages parameter to support node allocation", but the
following problem is observed.
Confusing behavior is observed when both 1G and 2M hugepage is set
after "numa=off".
cmdline hugepage settings:
hugepagesz=1G hugepages=0:3,1:3
hugepagesz=2M hugepages=0:1024,1:1024
results:
HugeTLB registered 1.00 GiB page size, pre-allocated 0 pages
HugeTLB registered 2.00 MiB page size, pre-allocated 1024 pages
Furthermore, confusing behavior can be also observed when an invalid node
behind a valid node. To fix this, never allocate any typical hugepage
when an invalid parameter is received.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
