39 | Direct Access (DAX) can be used on memory-backed block devices. | |
40 | If the block device supports DAX and the filesystem supports DAX, | |
41 | then you can avoid using the pagecache to buffer I/Os. Turning | |
42 | on this option will compile in support for DAX; you will need to | |
43 | mount the filesystem using the -o dax option. | |
44 | ||
45 | If you do not have a block device that is capable of using this, | |
46 | or if unsure, say N. Saying Y will increase the size of the kernel | |

132 | Tmpfs is a file system which keeps all files in virtual memory. | |
133 | ||
134 | Everything in tmpfs is temporary in the sense that no files will be | |
135 | created on your hard drive. The files live in memory and swap | |
136 | space. If you unmount a tmpfs instance, everything stored therein is | |
137 | lost. | |

147 | POSIX Access Control Lists (ACLs) support additional access rights |
148 | for users and groups beyond the standard owner/group/world scheme, | |
149 | and this option selects support for ACLs specifically for tmpfs | |
150 | filesystems. | |
151 | ||
152 | If you've selected TMPFS, it's possible that you'll also need | |
153 | this option as there are a number of Linux distros that require | |
154 | POSIX ACL support under /dev for certain features to work properly. | |
155 | For example, some distros need this feature for ALSA-related /dev | |
156 | files for sound to work properly. In short, if you're not sure, | |
157 | say Y. | |
