  "message": "ore/exofs: Change the type of the devices array (API change)\n\nIn the pNFS obj-LD the device table at the layout level needs\nto point to a device_cache node, where it is possible and likely\nthat many layouts will point to the same device-nodes.\n\nIn Exofs we have a more orderly structure where we have a single\narray of devices that repeats twice for a round-robin view of the\ndevice table\n\nThis patch moves to a model that can be used by the pNFS obj-LD\nwhere struct ore_components holds an array of ore_dev-pointers.\n(ore_dev is newly defined and contains a struct osd_dev *od\n member)\n\nEach pointer in the array of pointers will point to a bigger\nuser-defined dev_struct. That can be accessed by use of the\ncontainer_of macro.\n\nIn Exofs an __alloc_dev_table() function allocates the\nore_dev-pointers array as well as an exofs_dev array, in one\nallocation and does the addresses dance to set everything pointing\ncorrectly. It still keeps the double allocation trick for the\ninodes round-robin view of the table.\n\nThe device table is always allocated dynamically, also for the\nsingle device case. So it is unconditionally freed at umount.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n",
