- 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.

-config BTRFS_FS_POSIX_ACL

- select FS_POSIX_ACL
- help
- 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/>.
-
- If you don't know what Access Control Lists are, say N

-config BTRFS_FS_CHECK_INTEGRITY
- 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
