  6. Stores not just filenames but the files themselves in a balanced
  7. tree. Uses journalling.
  8. Balanced trees are more efficient than traditional file system
  9. architectural foundations.
  10. In general, ReiserFS is as fast as ext2, but is very efficient with
  11. large directories and small files. Additional patches are needed
  12. for NFS and quotas, please see
  13. <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
  14. It is more easily extended to have features currently found in
  15. database and keyword search systems than block allocation based file
  16. systems are. The next version will be so extended, and will support
  17. plugins consistent with our motto ``It takes more than a license to
  18. make source code open.''

  23. need, buy a support contract, or pay us to port it to another OS.

  28. If you set this to Y, then ReiserFS will perform every check it can
  29. possibly imagine of its internal consistency throughout its
  30. operation. It will also go substantially slower. More than once we
  31. have forgotten that this was on, and then gone despondent over the
  32. latest benchmarks.:-) Use of this option allows our team to go all
  33. out in checking for consistency when debugging without fear of its
  34. effect on end users. If you are on the verge of sending in a bug
  35. report, say Y and you might get a useful error message. Almost
  36. everyone should say N.

  40. help
  41. Create under /proc/fs/reiserfs a hierarchy of files, displaying
  42. various ReiserFS statistics and internal data at the expense of
  43. making your kernel or module slightly larger (+8 KB). This also
  44. increases the amount of kernel memory required for each mount.
  45. Almost everyone but ReiserFS developers and people fine-tuning
  46. reiserfs or tracing problems should say N.

  51. Extended attributes are name:value pairs associated with inodes by
  52. the kernel or by users (see the attr(5) manual page for details).
  53. If unsure, say N.

  59. Posix Access Control Lists (ACLs) support permissions for users and
  60. groups beyond the owner/group/world scheme.

  62. config REISERFS_FS_SECURITY

  64. depends on REISERFS_FS_XATTR
  65. help
  66. Security labels support alternative access control models
  67. implemented by security modules like SELinux. This option
  68. enables an extended attribute handler for file security
  69. labels in the ReiserFS filesystem.
  70. If you are not using a security module that requires using
  71. extended attributes for file security labels, say N.
