Subject[PATCH 2/2] Staging: android: binder: Don't call dump_stack in binder_vma_open
Date
If user-space partially unmaps the driver, binder_vma_open
would dump the kernel stack. This is not a kernel bug however
and will be treated as if the whole area was unmapped once
binder_vma_close gets called.
