Merge tag 'liveupdate-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/liveupdate/linuxPull liveupdate updates from Mike Rapoport: "Kexec Handover: - Fix size calculation in kho_preserved_memory_reserve() for preservations larger than 2 GiB Live Update Orchestrator: - move liveupdate selftest utilities into a library so that selftests of subsystems participating in liveupdate, e.g. PCI and VFIO, can use them and drop direct ioctl calls from the tests - add end to end liveupdate test infrastructure that allows running the tests across a kexec in QEMU - remove redundant INIT_LIST_HEAD in luo_session_alloc() - remember the error status of an FLB retrieve() and return it on subsequent attempts rather than retrying retrieve() with an FLB in an unexpected state - reference count the outgoing FLB so that it cannot be freed while a caller is using it, the same way it's done for the incoming FLB - reject nonzero reserved field in LIVEUPDATE_SESSION_FINISH so that it can be reused by a future extension"* tag 'liveupdate-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/liveupdate/linux: kho: fix size calculation in kho_preserved_memory_reserve() selftests/liveupdate: Move luo_test_utils.* into a reusable library selftests/liveupdate: Use luo_test_utils.c for liveupdate ioctl APIs liveupdate: Remember FLB retrieve() status liveupdate: Reference count outgoing FLB data liveupdate: reject nonzero reserved value for SESSION_FINISH liveupdate: Remove redundant INIT_LIST_HEAD in luo_session_alloc selftests/liveupdate: add end to end test infrastructure and scripts List of files: /linux/tools/testing/selftests/liveupdate/lib/lu_utils.c

selftests/liveupdate: Move luo_test_utils.* into a reusable libraryMove luo_test_utils.[ch] into a lib/ directory and make libliveupdatelibrary. Pull the rules to build them out into a separatelibliveupdate.mk script. This will enable these utilities to bealso built by and used within other selftests (such as VFIO).Update path in vmtest.sh as that one uses hardcoded path for util.No functional change intended.Co-developed-by: David Matlack Signed-off-by: David Matlack Acked-by: Pratyush Yadav (Google) Reviewed-by: Pasha Tatashin Signed-off-by: Vipin Sharma Link: https://patch.msgid.link/20260720203202.1964557-3-vipinsh@google.comSigned-off-by: Mike Rapoport (Microsoft) List of files: /linux/tools/testing/selftests/liveupdate/lib/lu_utils.c
