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

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

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