+config FUSE_FS
+ tristate "FUSE (Filesystem in Userspace) support"
+ select FS_POSIX_ACL
+ select FS_IOMAP
+ help
+ With FUSE it is possible to implement a fully functional filesystem
+ in a userspace program.
+
+ There's also a companion library: libfuse2. This library is available
+ from the FUSE homepage:
+ <https://github.com/libfuse/>
+ although chances are your distribution already has that library
+ installed if you've installed the "fuse" package itself.
+
+ See <file:Documentation/filesystems/fuse/fuse.rst> for more information.
+ See <file:Documentation/Changes> for needed library/utility version.
+
+ If you want to develop a userspace FS, or if you want to use
+ a filesystem based on FUSE, answer Y or M.
+
+config CUSE
+ tristate "Character device in Userspace support"
+ depends on FUSE_FS
+ help
+ This FUSE extension allows character devices to be
+ implemented in userspace.
+
+ If you want to develop or use a userspace character device
+ based on CUSE, answer Y or M.
+
+config VIRTIO_FS
+ tristate "Virtio Filesystem"
+ depends on FUSE_FS
+ select VIRTIO
+ help
+ The Virtio Filesystem allows guests to mount file systems from the
+ host.
+
+ If you want to share files between guests or with the host, answer Y
+ or M.
+
+config FUSE_DAX
+ bool "Virtio Filesystem Direct Host Memory Access support"
+ default y
+ select INTERVAL_TREE
+ depends on VIRTIO_FS
+ depends on FS_DAX
+ depends on DAX
+ help
+ This allows bypassing guest page cache and allows mapping host page
+ cache directly in guest address space.
+
+ If you want to allow mounting a Virtio Filesystem with the "dax"
+ option, answer Y.
+
+config FUSE_PASSTHROUGH
+ bool "FUSE passthrough operations support"
+ default y
+ depends on FUSE_FS
+ select FS_STACK
+ help
+ This allows bypassing FUSE server by mapping specific FUSE operations
+ to be performed directly on a backing file.
+
+ If you want to allow passthrough operations, answer Y.
+
+config FUSE_IO_URING
+ bool "FUSE communication over io-uring"
+ default y
+ depends on FUSE_FS
+ depends on IO_URING
+ help
+ This allows sending FUSE requests over the io-uring interface and
+ also adds request core affinity.
+
+ If you want to allow fuse server/client communication through io-uring,
+ answer Y
