mtd/fs/Config.in contains
dep_tristate 'Journalling Flash File System (JFFS) support' CONFIG_JFFS_FS
$CONFIG_MTD
if [ "$CONFIG_JFFS_FS" = "y" -o "$CONFIG_JFFS_FS" = "m" ] ; then
int 'JFFS debugging verbosity (0 = quiet, 3 = noisy)'
CONFIG_JFFS_FS_VERBOSE 0
bool 'JFFS stats available in /proc filesystem' CONFIG_JFFS_PROC_FS
fi
dep_tristate 'Journalling Flash File System v2 (JFFS2) support'
CONFIG_JFFS2_FS $CONFIG_MTD
if [ "$CONFIG_JFFS2_FS" = "y" -o "$CONFIG_JFFS2_FS" = "m" ] ; then
int 'JFFS2 debugging verbosity (0 = quiet, 2 = noisy)'
CONFIG_JFFS2_FS_DEBUG 0
bool 'JFFS2 support for NAND chips' CONFIG_JFFS2_FS_NAND
fi
This is patched into the linux/fs/Config.in by the patchin.sh script, which
can be found in mtd/patches. It's recommended to use this script.
