But such a vma can be shrunk by\nan munmap(2). The current driver uses the current size of each vma to\ndeduce whether its vma_data structure was allocated by kmalloc() or vmalloc().\nSo if the vma was shrunk it appears to have been allocated by kmalloc(),\nand mspec attempts to free it with kfree(). This results in a panic.\n\nThis patch avoids the panic (by preserving the type of the allocation) and\nalso makes mspec work correctly as the vma is split into pieces by the\nmunmap(2)\u0027s.\n\nAll vma\u0027s derived from such a split vma share the same vma_data structure that\nrepresents all the pages mapped into this set of vma\u0027s. The mpec driver\nmust be made capable of using the right portion of the structure for each\nmember vma. In other words, it must index into the array of page addresses\nusing the portion of the array that represents the current vma.
