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

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

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