Ensure I/O buffers in libufs(3) are 128-byte aligned.
Various disk controllers require their buffers to be aligned to a cache-line size (128 bytes). For buffers allocated in structures, ensure that they are 128-byte aligned. Use aligned_malloc to allocate memory to ensure that the returned memory is 128-byte aligned. While we are here, we replace the dynamically allocated inode buffer with a buffer allocated in the uufsd structure just as the superblock and cylinder group buffers do. This can be removed if/when the kernel is fixed. Because this problem has existed on one I/O subsystem or another since the 1990's, we are probably stuck with dealing with it forever. The problem most recent showed up in Azure, see: https://reviews.freebsd.org/D41728 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267654 Before these fixes were applied, it was confirmed that the changes in this commit also fixed the issue in Azure.
