Kefeng Wang 4c6c002042 riscv: mm: accelerate pagefault when badaccess ... The access_error() of vma already checked under per-VMA lock, if it is a bad access, directly handle error, no need to retry with mmap_lock again. Since the page faut is handled under per-VMA lock, count it as a vma lock event with VMA_LOCK_SUCCESS.
