43 | Direct Access (DAX) can be used on memory-backed block devices. | |
44 | If the block device supports DAX and the filesystem supports DAX, | |
45 | then you can avoid using the pagecache to buffer I/Os. Turning | |
46 | on this option will compile in support for DAX; you will need to | |
47 | mount the filesystem using the -o dax option. | |
48 | ||
49 | If you do not have a block device that is capable of using this, | |

143 | Tmpfs is a file system which keeps all files in virtual memory. | |
144 | ||
145 | Everything in tmpfs is temporary in the sense that no files will be | |
146 | created on your hard drive. The files live in memory and swap | |
147 | space. If you unmount a tmpfs instance, everything stored therein is | |
148 | lost. | |

158 | POSIX Access Control Lists (ACLs) support additional access rights | |

161 | filesystems. | |
162 | ||
163 | If you've selected TMPFS, it's possible that you'll also need | |
164 | this option as there are a number of Linux distros that require | |
165 | POSIX ACL support under /dev for certain features to work properly. | |
166 | For example, some distros need this feature for ALSA-related /dev | |
167 | files for sound to work properly. In short, if you're not sure, | |
168 | say Y. | |
