1173 select CRC32
1174 depends on MTD
1175 help
1176 JFFS2 is the second generation of the Journalling Flash File System
1177 for use on diskless embedded devices. It provides improved wear
1178 levelling, compression and support for hard links. You cannot use
1179 this on normal block devices, only on 'MTD' devices.
1180
1181 Further information on the design and implementation of JFFS2 is
1182 available at <http://sources.redhat.com/jffs2/>.

1186 depends on JFFS2_FS
1187 default "0"
1188 help
1189 This controls the amount of debugging messages produced by the JFFS2
1190 code. Set it to zero for use in production systems. For evaluation,
1191 testing and debugging, it's advisable to set it to one. This will
1192 enable a few assertions and will print debugging messages at the
1193 KERN_DEBUG loglevel, where they won't normally be visible. Level 2
1194 is unlikely to be useful - it enables extra debugging in certain
1195 areas which at one point needed debugging, but when the bugs were
1196 located and fixed, the detailed messages were relegated to level 2.
1197
1198 If reporting bugs, please try to have available a full dump of the
1199 messages at debug level 1 while the misbehaviour was occurring.

1205 help
1206 This enables the write-buffering support in JFFS2.
1207
1208 This functionality is required to support JFFS2 on the following
1209 types of flash devices:
1210 - NAND flash
1211 - NOR flash with transparent ECC
1212 - DataFlash

1228 for faster filesystem mount.
1229
1230 The summary information can be inserted into a filesystem image
1231 by the utility 'sumtool'.

1267 enables an extended attribute handler for file security
1268 labels in the jffs2 filesystem.

1277 help
1278 Enabling this option allows you to explicitly choose which
1279 compression modules, if any, are enabled in JFFS2. Removing
1280 compressors can mean you cannot read existing file systems,
1281 and enabling experimental compressors can mean that you
1282 write a file system which cannot be read by a standard kernel.
