35 bool "Direct Access (DAX) support"
37 depends on !(ARM || MIPS || SPARC)
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.
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

69 bool "Enable POSIX file locking API" if EXPERT
72 This option enables standard file locking support, required
73 for filesystems like NFS and for the flock() system
74 call. Disabling this option saves about 11k.

121 Tmpfs is a file system which keeps all files in virtual memory.
123 Everything in tmpfs is temporary in the sense that no files will be
124 created on your hard drive. The files live in memory and swap
125 space. If you unmount a tmpfs instance, everything stored therein is
128 See <file:Documentation/filesystems/tmpfs.txt> for details.

131 bool "Tmpfs POSIX Access Control Lists"
136 POSIX Access Control Lists (ACLs) support additional access rights
137 for users and groups beyond the standard owner/group/world scheme,
138 and this option selects support for ACLs specifically for tmpfs
141 If you've selected TMPFS, it's possible that you'll also need
142 this option as there are a number of Linux distros that require
143 POSIX ACL support under /dev for certain features to work properly.
144 For example, some distros need this feature for ALSA-related /dev
145 files for sound to work properly. In short, if you're not sure,
148 To learn more about Access Control Lists, visit the POSIX ACLs for
149 Linux website <http://acl.bestbits.at/>.
152 bool "Tmpfs extended attributes"
156 Extended attributes are name:value pairs associated with inodes by
157 the kernel or by users (see the attr(5) manual page, or visit
158 <http://acl.bestbits.at/> for details).
160 Currently this enables support for the trusted.* and
161 security.* namespaces.
163 You need this for POSIX ACL support on tmpfs.
