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

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

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