  "message": "hugetlbfs: fix i_blocks accounting\n\nAs reported in Red Hat bz #509671, i_blocks for files on hugetlbfs get\naccounting wrong when doing something like:\n\n   $ \u003e foo\n   $ date  \u003e foo\n   date: write error: Invalid argument\n   $ /usr/bin/stat foo\n     File: `foo\u0027\n     Size: 0          Blocks: 18446744073709547520 IO Block: 2097152 regular\n...\n\nThis is because hugetlb_unreserve_pages() is unconditionally removing\nblocks_per_huge_page(h) on each call rather than using the freed amount.\nIf there were 0 blocks, it goes negative, resulting in the above.\n\nThis is a regression from commit a5516438959d90b071ff0a484ce4f3f523dc3152\n(\"hugetlb: modular state for hugetlb page size\")\n\nwhich did:\n\n-\tinode-\u003ei_blocks -\u003d BLOCKS_PER_HUGEPAGE * freed;\n+\tinode-\u003ei_blocks -\u003d blocks_per_huge_page(h);\n\nso just put back the freed multiplier, and it\u0027s all happy again.\n\nSigned-off-by: Eric Sandeen \u003csandeen@redhat.com\u003e\nAcked-by: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
