  "message": "md: Relax minimum size restrictions on chunk_size.\n\nCurrently, the \u0027chunk_size\u0027 of an array must be at-least PAGE_SIZE.\n\nThis makes moving an array to a machine with a larger PAGE_SIZE, or\nchanging the kernel to use a larger PAGE_SIZE, can stop an array from\nworking.\n\nFor RAID10 and RAID4/5/6, this is non-trivial to fix as the resync\nprocess works on whole pages at a time, and assumes them to be wholly\nwithin a stripe.  For other raid personalities, this restriction is\nnot needed at all and can be dropped.\n\nSo remove the test on chunk_size from common can, and add it in just\nthe places where it is needed: raid10 and raid4/5/6.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\n",
