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

71 bool "Enable filesystem export operations for block IO"
73 This option enables the export operations for a filesystem to support
77 bool "Enable POSIX file locking API" if EXPERT
80 This option enables standard file locking support, required
81 for filesystems like NFS and for the flock() system
82 call. Disabling this option saves about 11k.

136 bool "Tmpfs virtual memory file system support (former shm fs)"
139 Tmpfs is a file system which keeps all files in virtual memory.
141 Everything in tmpfs is temporary in the sense that no files will be
142 created on your hard drive. The files live in memory and swap
143 space. If you unmount a tmpfs instance, everything stored therein is
146 See <file:Documentation/filesystems/tmpfs.txt> for details.
148 config TMPFS_POSIX_ACL
149 bool "Tmpfs POSIX Access Control Lists"
154 POSIX Access Control Lists (ACLs) support additional access rights
155 for users and groups beyond the standard owner/group/world scheme,
156 and this option selects support for ACLs specifically for tmpfs
159 If you've selected TMPFS, it's possible that you'll also need
160 this option as there are a number of Linux distros that require
161 POSIX ACL support under /dev for certain features to work properly.
162 For example, some distros need this feature for ALSA-related /dev
163 files for sound to work properly. In short, if you're not sure,
166 To learn more about Access Control Lists, visit the POSIX ACLs for
167 Linux website <http://acl.bestbits.at/>.
170 bool "Tmpfs extended attributes"
174 Extended attributes are name:value pairs associated with inodes by
175 the kernel or by users (see the attr(5) manual page, or visit
176 <http://acl.bestbits.at/> for details).
178 Currently this enables support for the trusted.* and
179 security.* namespaces.
181 You need this for POSIX ACL support on tmpfs.
