44 | Direct Access (DAX) can be used on memory-backed block devices. | |
45 | If the block device supports DAX and the filesystem supports DAX, | |
46 | then you can avoid using the pagecache to buffer I/Os. Turning | |
47 | on this option will compile in support for DAX; you will need to | |
48 | mount the filesystem using the -o dax option. | |

150 | Tmpfs is a file system which keeps all files in virtual memory. | |
151 | ||
152 | Everything in tmpfs is temporary in the sense that no files will be | |
153 | created on your hard drive. The files live in memory and swap | |
154 | space. If you unmount a tmpfs instance, everything stored therein is | |

168 | filesystems. | |
169 | ||
170 | If you've selected TMPFS, it's possible that you'll also need | |
171 | this option as there are a number of Linux distros that require | |
172 | POSIX ACL support under /dev for certain features to work properly. | |
173 | For example, some distros need this feature for ALSA-related /dev | |
174 | files for sound to work properly. In short, if you're not sure, | |
175 | say Y. | |
