      "message": "block: blk_max_pfn is somtimes wrong\n\nThere is a small problem in handling page bounce.\n\nAt the moment blk_max_pfn equals max_pfn, which is in fact not maximum\npossible _number_ of a page frame, but the _amount_ of page frames.  For\nexample for the 32bit x86 node with 4Gb RAM, max_pfn \u003d 0x100000, but not\n0xFFFF.\n\nrequest_queue structure has a member q-\u003ebounce_pfn and queue needs bounce\npages for the pages _above_ this limit.  This routine is handled by\nblk_queue_bounce(), where the following check is produced:\n\n\tif (q-\u003ebounce_pfn \u003e\u003d blk_max_pfn)\n\t\treturn;\n\nAssume, that a driver has set q-\u003ebounce_pfn to 0xFFFF, but blk_max_pfn\nequals 0x10000.  In such situation the check above fails and for each bio\nwe always fall down for iterating over pages tied to the bio.\n\nI want to notice, that for quite a big range of device drivers (ide, md,\n...) such problem doesn\u0027t happen because they use BLK_BOUNCE_ANY for\nbounce_pfn.  BLK_BOUNCE_ANY is defined as blk_max_pfn \u003c\u003c PAGE_SHIFT, and\nthen the check above doesn\u0027t fail.  But for other drivers, which obtain\nreuired value from drivers, it fails.  For example sata_nv uses\nATA_DMA_MASK or dev-\u003edma_mask.\n\nI propose to use (max_pfn - 1) for blk_max_pfn.  And the same for\nblk_max_low_pfn.  The patch also cleanses some checks related with\nbounce_pfn.\n\nSigned-off-by: Vasily Tarasov \u003cvtaras@openvz.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n"
