If do_mmap_shared_file() or\ndo_mmap_private() fail, we jump to the error_put_region label at which\npoint we cann __put_nommu_region() on the region - but we haven\u0027t yet\nadded the region to the tree, and so __put_nommu_region() may BUG\nbecause the region tree is empty or it may corrupt the region tree.\n\nTo get around this, we can afford to add the region to the region tree\nbefore calling do_mmap_shared_file() or do_mmap_private() as we keep\nnommu_region_sem write-locked, so no-one can race with us by seeing a\ntransient region.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nAcked-by: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Greg Ungerer \u003cgerg@snapgear.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
