58 help
59 Direct Access (DAX) can be used on memory-backed block devices.
60 If the block device supports DAX and the filesystem supports DAX,
61 then you can avoid using the pagecache to buffer I/Os. Turning
62 on this option will compile in support for DAX.
63
64 For a DAX device to support file system access it needs to have
65 struct pages. For the nfit based NVDIMMs this can be enabled
66 using the ndctl utility:
67
68 # ndctl create-namespace --force --reconfig=namespace0.0 \
69 --mode=fsdax --map=mem
70
71 See the 'create-namespace' man page for details on the overhead of
72 --map=mem:
73 https://docs.pmem.io/ndctl-user-guide/ndctl-man-pages/ndctl-create-namespace
74
75 For ndctl to work CONFIG_DEV_DAX needs to be enabled as well. For most
76 file systems DAX support needs to be manually enabled globally or
77 per-inode using a mount option as well. See the file documentation in
78 Documentation/filesystems/dax.rst for details.
79
80 If you do not have a block device that is capable of using this,
81 or if unsure, say N. Saying Y will increase the size of the kernel
82 by about 5kB.

172 help
173 Tmpfs is a file system which keeps all files in virtual memory.
174
175 Everything in tmpfs is temporary in the sense that no files will be
176 created on your hard drive. The files live in memory and swap
177 space. If you unmount a tmpfs instance, everything stored therein is
178 lost.

188 POSIX Access Control Lists (ACLs) support additional access rights
189 for users and groups beyond the standard owner/group/world scheme,
190 and this option selects support for ACLs specifically for tmpfs
191 filesystems.
192
193 If you've selected TMPFS, it's possible that you'll also need
194 this option as there are a number of Linux distros that require
195 POSIX ACL support under /dev for certain features to work properly.
196 For example, some distros need this feature for ALSA-related /dev
197 files for sound to work properly. In short, if you're not sure,
198 say Y.

216 bool "Use 64-bit ino_t by default in tmpfs"
217 depends on TMPFS && 64BIT
218 default n
219 help
220 tmpfs has historically used only inode numbers as wide as an unsigned
221 int. In some cases this can cause wraparound, potentially resulting
222 in multiple files with the same inode number on a single device. This
223 option makes tmpfs use the full width of ino_t by default, without
224 needing to specify the inode64 option when mounting.
225
226 But if a long-lived tmpfs is to be accessed by 32-bit applications so
227 ancient that opening a file larger than 2GiB fails with EINVAL, then
228 the INODE64 config option and inode64 mount option risk operations
229 failing with EOVERFLOW once 33-bit inode numbers are reached.
230
231 To override this configured default, use the inode32 or inode64
232 option when mounting.
233
234 If unsure, say N.
