Hi All I have just checked in a change which allows the control of garbage collection. This can be controlled via sysfs interface At present there is only one bit being used but more bits will likely be added in the future. Disable gc # echo 0 > /sys/module/yaffs/parameters/yaffs_gc_control Enable gc # echo 1 > /sys/module/yaffs/parameters/yaffs_gc_control Disabling gc is generally not advised, but it can be used to write faster during power down conditions etc. -- Charles
