-config AUFS_FS
- tristate "Aufs (Advanced multi layered unification filesystem) support"
- help
- Aufs is a stackable unification filesystem such as Unionfs,
- which unifies several directories and provides a merged single
- directory.
- In the early days, aufs was entirely re-designed and
- re-implemented Unionfs Version 1.x series. Introducing many
- original ideas, approaches and improvements, it becomes totally
- different from Unionfs while keeping the basic features.

- prompt "Maximum number of branches"
- default AUFS_BRANCH_MAX_127
- help
- Specifies the maximum number of branches (or member directories)
- in a single aufs. The larger value consumes more system
- resources and has a minor impact to performance.
-config AUFS_BRANCH_MAX_127

- resources and has a minor impact to performance.

-config AUFS_SBILIST

- default y
- help
- Automatic configuration for internal use.
- When aufs supports Magic SysRq or /proc, enabled automatically.
-
-config AUFS_HNOTIFY
- bool "Detect direct branch access (bypassing aufs)"
- help
- If you want to modify files on branches directly, eg. bypassing aufs,
- and want aufs to detect the changes of them fully, then enable this
- option and use 'udba=notify' mount option.
- Currently there is only one available configuration, "fsnotify".
- It will have a negative impact to the performance.
- See detail in aufs.5.

-config AUFS_EXPORT
- bool "NFS-exportable aufs"
- depends on EXPORTFS
- help
- If you want to export your mounted aufs via NFS, then enable this
- option. There are several requirements for this configuration.
- See detail in aufs.5.

-config AUFS_XATTR
- bool "support for XATTR/EA (including Security Labels)"
- help
- If your branch fs supports XATTR/EA and you want to make them
- available in aufs too, then enable this opsion and specify the
- branch attributes for EA.
- See detail in aufs.5.
-
-config AUFS_FHSM
- bool "File-based Hierarchical Storage Management"
- help
- Hierarchical Storage Management (or HSM) is a well-known feature
- in the storage world. Aufs provides this feature as file-based.
- with multiple branches.
- These multiple branches are prioritized, ie. the topmost one
- should be the fastest drive and be used heavily.
-
-config AUFS_RDU
- bool "Readdir in userspace"
- help
- Aufs has two methods to provide a merged view for a directory,
- by a user-space library and by kernel-space natively. The latter
- is always enabled but sometimes large and slow.
- If you enable this option, install the library in aufs2-util
- package, and set some environment variables for your readdir(3),
- then the work will be handled in user-space which generally
- shows better performance in most cases.
- See detail in aufs.5.
-
-config AUFS_SHWH
- bool "Show whiteouts"
- help
- If you want to make the whiteouts in aufs visible, then enable
- this option and specify 'shwh' mount option. Although it may
- sounds like philosophy or something, but in technically it
- simply shows the name of whiteout with keeping its behaviour.
-
-config AUFS_BR_RAMFS
- bool "Ramfs (initramfs/rootfs) as an aufs branch"
- help
- If you want to use ramfs as an aufs branch fs, then enable this
- option. Generally tmpfs is recommended.
- Aufs prohibited them to be a branch fs by default, because
- initramfs becomes unusable after switch_root or something
- generally. If you sets initramfs as an aufs branch and boot your
- system by switch_root, you will meet a problem easily since the
- files in initramfs may be inaccessible.
- Unless you are going to use ramfs as an aufs branch fs without
- switch_root or something, leave it N.

-config AUFS_BR_FUSE
- bool "Fuse fs as an aufs branch"
- depends on FUSE_FS
- select AUFS_POLL
- help
- If you want to use fuse-based userspace filesystem as an aufs
- branch fs, then enable this option.
- It implements the internal poll(2) operation which is
- implemented by fuse only (curretnly).
-
-config AUFS_POLL

- Automatic configuration for internal use.

-config AUFS_BR_HFSPLUS
- bool "Hfsplus as an aufs branch"
- depends on HFSPLUS_FS
- default y
- help
- If you want to use hfsplus fs as an aufs branch fs, then enable
- this option. This option introduces a small overhead at
- copying-up a file on hfsplus.
