+ Btrfs is a new filesystem with extents, writable snapshotting,
+ support for multiple devices and many more features.
+
+ Btrfs is highly experimental, and THE DISK FORMAT IS NOT YET
+ FINALIZED. You should say N here unless you are interested in
+ testing Btrfs with non-critical data.
+
+ To compile this file system support as a module, choose M here. The
+ module will be called btrfs.
+
+ If unsure, say N.

+ POSIX Access Control Lists (ACLs) support permissions for users and
+ groups beyond the owner/group/world scheme.
+
+ To learn more about Access Control Lists, visit the POSIX ACLs for
+ Linux website <http://acl.bestbits.at/>.

+ bool "Btrfs with integrity check tool compiled in (DANGEROUS)"
+ depends on BTRFS_FS
+ help
+ Adds code that examines all block write requests (including
+ writes of the super block). The goal is to verify that the
+ state of the filesystem on disk is always consistent, i.e.,
+ after a power-loss or kernel panic event the filesystem is
+ in a consistent state.
+
+ If the integrity check tool is included and activated in
+ the mount options, plenty of kernel memory is used, and
+ plenty of additional CPU cycles are spent. Enabling this
+ functionality is not intended for normal use.
+
+ In most cases, unless you are a btrfs developer who needs
+ to verify the integrity of (super)-block write requests
+ during the run of a regression test, say N
