10 Btrfs is a new filesystem with extents, writable snapshotting,
11 support for multiple devices and many more features.
12
13 Btrfs is highly experimental, and THE DISK FORMAT IS NOT YET
14 FINALIZED. You should say N here unless you are interested in
15 testing Btrfs with non-critical data.
16
17 To compile this file system support as a module, choose M here. The
18 module will be called btrfs.
19
20 If unsure, say N.

39 Adds code that examines all block write requests (including
40 writes of the super block). The goal is to verify that the
41 state of the filesystem on disk is always consistent, i.e.,
42 after a power-loss or kernel panic event the filesystem is
43 in a consistent state.
44
45 If the integrity check tool is included and activated in
46 the mount options, plenty of kernel memory is used, and
47 plenty of additional CPU cycles are spent. Enabling this
48 functionality is not intended for normal use.
49
50 In most cases, unless you are a btrfs developer who needs
51 to verify the integrity of (super)-block write requests
52 during the run of a regression test, say N
