40 | help |
41 | Direct Access (DAX) can be used on memory-backed block devices. | |
42 | If the block device supports DAX and the filesystem supports DAX, | |
43 | then you can avoid using the pagecache to buffer I/Os. Turning | |
44 | on this option will compile in support for DAX; you will need to | |
45 | mount the filesystem using the -o dax option. | |
46 | ||
47 | If you do not have a block device that is capable of using this, | |
48 | or if unsure, say N. Saying Y will increase the size of the kernel | |
49 | by about 5kB. | |

115 | Tmpfs is a file system which keeps all files in virtual memory. | |

117 | Everything in tmpfs is temporary in the sense that no files will be | |

119 | space. If you unmount a tmpfs instance, everything stored therein is | |
120 | lost. | |

130 | POSIX Access Control Lists (ACLs) support additional access rights |
131 | for users and groups beyond the standard owner/group/world scheme, | |
132 | and this option selects support for ACLs specifically for tmpfs | |
133 | filesystems. | |
134 | ||
135 | If you've selected TMPFS, it's possible that you'll also need | |
136 | this option as there are a number of Linux distros that require | |
137 | POSIX ACL support under /dev for certain features to work properly. | |
138 | For example, some distros need this feature for ALSA-related /dev | |
139 | files for sound to work properly. In short, if you're not sure, | |
140 | say Y. | |
