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

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

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