![]() In the quest to remove all stack VLA usage from the kernel[1], this allocates the maximum size stack buffer. Existing checks already require that blocksize >= NTFS_BLOCK_SIZE and mft_record_size <= PAGE_SIZE, so max_bhs can be at most PAGE_SIZE / NTFS_BLOCK_SIZE. Sanity checks are added for robustness.
