Hi Linus,
This PR adds support for Landlock to UML. In fact, this fixes the way
hostfs manages inodes according to the underlying filesystem [1]. They
are now properly handled as for other filesystems, which enables to
support Landlock (and probably other features). This PR also extends
Landlock's tests with 6 pseudo filesystems, including hostfs.
This PR can lead to a trivial merge conflict with tip [2] where one of
Thomas's commit adds ARCH_HAS_CPU_FINALIZE_INIT and one of mine removes
ARCH_EPHEMERAL_INODES in arch/um/Kconfig.
Please pull these changes for v6.5-rc1 . These commits merged cleanly
with v6.4, and have been successfully tested in the latest linux-next
releases for a few weeks.
