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.

84 To the best of my knowledge this is dead code that no one cares about.

126 bool "Tmpfs virtual memory file system support (former shm fs)"
129 Tmpfs is a file system which keeps all files in virtual memory.
131 Everything in tmpfs is temporary in the sense that no files will be
132 created on your hard drive. The files live in memory and swap
133 space. If you unmount a tmpfs instance, everything stored therein is

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