Wed, 15 Apr 2026 14:27:31 +0200

tools/testing/memblock: fix stale NUMA reservation testsmemblock allocations now reserve memory with MEMBLOCK_RSRV_KERN and,on NUMA configurations, record the requested node on the reservedregion. Several memblock simulator NUMA tests still expected mergesthat only worked before those reservation semantics changed, so thesuite aborted even though the allocator behavior was correct.Update the NUMA merge expectations in the memblock_alloc_try_nid()and memblock_alloc_exact_nid_raw() tests to match the current reservedregion metadata rules. For cases that should still merge, create thepre-existing reservation with matching nid and MEMBLOCK_RSRV_KERNmetadata. Also strengthen the memblock_alloc_node() coverage bychecking the newly created reserved region directly instead ofre-reading the source memory node descriptor.Finally, drop the stale README/TODO notes that still claimedmemblock_alloc_node() could not be tested.The memblock simulator passes again with NUMA enabled after theseupdates.Signed-off-by: Priyanshu Kumar Link: https://patch.msgid.link/20260415122731.1768912-1-priyanshukumarpu@gmail.com[rppt: dropped unrelated changes]Signed-off-by: Mike Rapoport (Microsoft) List of files: /linux/tools/testing/memblock/README

memblock test: Modify the obsolete description in READMEThe VERBOSE option in Makefile has been moved, but there still have thedescription left in README. For now, we use `-v` options when runningmemblock test to print information, so using the new to replace theobsolete items.Signed-off-by: Shaoqin Huang Acked-by: Rebecca Mckeever Signed-off-by: Mike Rapoport Link: https://lore.kernel.org/r/20220729161125.190845-1-shaoqin.huang@intel.com List of files: /linux/tools/testing/memblock/README

Mon, 04 Jul 2022 06:06:55 +0200

memblock tests: Makefile: add arguments to control verbosityAdd VERBOSE and MEMBLOCK_DEBUG user-provided arguments. VERBOSE willenable verbose output from Memblock simulator. MEMBLOCK_DEBUG will enablememblock_dbg() messages.Update the help message to include VERBOSE and MEMBLOCK_DEBUG. Updatethe README to include VERBOSE. The README does not include all availableoptions and refers to the help message for the remaining options.Therefore, omit MEMBLOCK_DEBUG from README.Reviewed-by: David Hildenbrand Signed-off-by: Rebecca Mckeever Signed-off-by: Mike Rapoport Link: https://lore.kernel.org/r/5503f3efe82ecef5c99961a1d53003c8ad06cf27.1656907314.git.remckee0@gmail.com List of files: /linux/tools/testing/memblock/README
