commit bfd40eaff5ab ("mm: fix # vma_is_anonymous() false-positives"). # # create_mspace_with_base() in the trace above, utilizes ashmem, and with # ashmem, for shared mappings we use shmem_zero_setup(), which sets the # vma->vm_ops to &shmem_vm_ops. But for private ashmem mappings nothing # sets the vma->vm_ops. # # Looking at the problematic patch, it seems to add a requirement that one # call vma_set_anonymous() on a vma, otherwise the dummy_vm_ops will be # used. Using the dummy_vm_ops seem to triggger SIGBUS when traversing # unmapped pages. # # Thus, this patch adds a call to vma_set_anonymous() for ashmem private # mappings and seems to avoid the reported problem. # # Fixes: bfd40eaff5ab ("mm: fix vma_is_anonymous() false-positives") # Cc: Kirill Shutemov <kirill.shutemov@linux.intel.com> # Cc: Andrew Morton <akpm@linux-foundation.org> # Cc: Dmitry
