2 tristate "Btrfs filesystem (EXPERIMENTAL) Unstable disk format"
3 depends on EXPERIMENTAL
13 Btrfs is a new filesystem with extents, writable snapshotting,
14 support for multiple devices and many more features.
16 Btrfs is highly experimental, and THE DISK FORMAT IS NOT YET
17 FINALIZED. You should say N here unless you are interested in
18 testing Btrfs with non-critical data.
20 To compile this file system support as a module, choose M here. The
21 module will be called btrfs.
25 config BTRFS_FS_POSIX_ACL
26 bool "Btrfs POSIX Access Control Lists"
30 POSIX Access Control Lists (ACLs) support permissions for users and
31 groups beyond the owner/group/world scheme.
33 To learn more about Access Control Lists, visit the POSIX ACLs for
34 Linux website <http://acl.bestbits.at/>.
36 If you don't know what Access Control Lists are, say N
38 config BTRFS_FS_CHECK_INTEGRITY
39 bool "Btrfs with integrity check tool compiled in (DANGEROUS)"
42 Adds code that examines all block write requests (including
43 writes of the super block). The goal is to verify that the
44 state of the filesystem on disk is always consistent, i.e.,
45 after a power-loss or kernel panic event the filesystem is
46 in a consistent state.
48 If the integrity check tool is included and activated in
49 the mount options, plenty of kernel memory is used, and
50 plenty of additional CPU cycles are spent. Enabling this
51 functionality is not intended for normal use.
53 In most cases, unless you are a btrfs developer who needs
54 to verify the integrity of (super)-block write requests
55 during the run of a regression test, say N
