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. | ||

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. | ||
