Uses journalling. 8 9 Balanced trees are more efficient than traditional file system 10 architectural foundations. 11 12 In general, ReiserFS is as fast as ext2, but is very efficient with 13 large directories and small files. Additional patches are needed 14 for NFS and quotas, please see 15 <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links. 16 17 It is more easily extended to have features currently found in 18 database and keyword search systems than block allocation based file 19 systems are. The next version will be so extended, and will support 20 plugins consistent with our motto ``It takes more than a license to 21 make source code open.'' 22 23 Read <https://reiser4.wiki.kernel.org/index.php/Main_Page> 24 to learn more about reiserfs. 25 26 Sponsored by Threshold Networks, Emusic.com, and Bigstorage.com. 27 28 If you like it, you can pay us to add new features to it that you 29 need, buy a support contract, or pay us to port it to another OS. 30 31config REISERFS_CHECK 32 bool "Enable reiserfs debug mode" 33 depends on REISERFS_FS 34 help 35 If you set this to Y, then ReiserFS will perform every check it can 36 possibly imagine of its internal consistency throughout its 37 operation. It will also go substantially slower. More than once we 38 have forgotten that this was on, and then gone despondent over the 39 latest benchmarks.:-) Use of this option allows our team to go all 40 out in checking for consistency when debugging without fear of its 41 effect on end users. If you are on the verge of sending in a bug 42 report, say Y and you might get a useful error message. Almost 43 everyone should say N. 44 45config REISERFS_PROC_INFO 46 bool "Stats in /proc/fs/reiserfs" 47 depends on REISERFS_FS && PROC_FS 48 help 49 Create under /proc/fs/reiserfs a hierarchy of files, displaying 50 various ReiserFS statistics and internal data at the expense of 51 making your kernel or module slightly larger (+8 KB).
