Public bug reported:
[Impact]
Some workloads, for example SQL Server, require PMEM support from
different modules for performance reasons. Most of this modules are
included in the linux-modules-extra package but linux-azure doesn't
install it by default.
Move these modules to the linux-modules package so they are installed by
default: nd_blk.ko, nd_pmem.ko, device_dax.ko, dax_hmem.ko, kmem.ko,
dax_pmem.ko, dax_pmem_compat.ko, virtio_pmem.ko , nd_virtio.ko.
(Some modules are not available depending on the kernel version)
[Test Plan]
The modules listed below should be included in the linux-modules package
instead of in the linux-modules-extra package.
[Where problems could occur]
The additional modules shouldn't cause any troubles and in case of
problem they can be blacklisted or removed from linux-modules.
