Oleg Nesterov 7a5bfb66b0 uprobes: Change build_map_info() to try kmalloc(GFP_NOWAIT) first ... build_map_info() doesn't allocate the memory under i_mmap_mutex to avoid the deadlock with page reclaim. But it can try GFP_NOWAIT first, it should work in the likely case and thus we almost never need the pre-alloc-and-retry path.
