Hi all,
    On our uClinux based target, we were using compressed RAMFS image and
have recently tried to go with uncompressed image. But this is eating up a
lot of RAM now.
    The image exists in flash, then the kernel is copied to RAM at boot up
and then the file system is extracted from the kernel. 
    After the file system is extracted to RAM, the space used up by the file
system, within the kernel image is not freed up.
    Has anyone tried to free the RAM within the kernel space, which held the
original file system?
    Its at location given by "__ramdisk_data" on our uClinux distro - from
NETSilicon/Redhat.
  Thanks for your time and feedback.

Abhishek
