We fixed minor bug which might cause incorrect operation of memory compaction code as well as merged some simple updates to memory reclaim function called by alloc_contig_range. I really hope that this will be a last iteration of this series. Best regards Marek Szyprowski Samsung Poland R&D Center Links to previous versions of the patchset: v20: v19: v18: v17: v16: v15: v14: v13: (internal, intentionally not released) v12: v11: v10: v9: v8: v7: v6: v5: (intentionally left out as CMA v5 was identical to CMA v4) v4: v3: v2: v1: Changelog: v21: 1. Fixed incorrect check which broke memory compaction code 2. Fixed hacky and racy min_free_kbytes handling 3. Added serialization patch to watermark calculation 4. Fixed typos here and there in the comments v20 and earlier - see previous patchsets.
