  "message": "xfs: Make fiemap work in query mode.\n\nAccording to Documentation/filesystems/fiemap.txt, If fm_extent_count\nis zero, then the fm_extents[] array is ignored (no extents will be\nreturned), and the fm_mapped_extents count will hold the number of\nextents needed.\n\nBut as the commit 97db39a1f6f69e906e98118392400de5217aa33a has changed\nbmv_count to the caller\u0027s input buffer, this number query function can\u0027t\nwork any more. As this commit is written to change bmv_count from\nMAXEXTNUM because of ENOMEM.\n\nThis patch just try to  set bm.bmv_count to something sane.\nThanks to Dave Chinner \u003cdavid@fromorbit.com\u003e for the suggestion.\n\nCc: Eric Sandeen \u003csandeen@redhat.com\u003e\nCc: Alex Elder \u003caelder@sgi.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Tao Ma \u003ctao.ma@oracle.com\u003e\n",
