Remove mmap_unaligned, which was used to heuristically decide whether to optimistically call mmap() in such a way that could reduce the total number of system calls. If I remember correctly, the intention of mmap_unaligned was to avoid always executing the slow path in the presence of ASLR. However, that reasoning seems to have been based on a flawed understanding of how ASLR actually works. Although ASLR apparently causes mmap() to ignore address requests, it does not cause total placement randomness, so there is a reasonable expectation that iterative mmap() calls will start returning chunk-aligned mappings once the first chunk has been properly aligned. |
