Hi Mulyadi,
I did some googling and found one clue that i have to change file system in
menuconfig file for EXT4 , which support both EXT2 and EXT3 as well,
so for that i have enable below features in file systems...
# CONFIG_EXT2_FS=n
# CONFIG_EXT3_FS=n
CONFIG_EXT4_USE_FOR_EXT2 3=Y
After
HI Mulyadi ,
Please find below my */proc/mounts* and */etc/fstab* files detail:

HI ALL:
I don't knowe why the linux designer need to define the ZONE_HIGHEM,
and why they defined it 896M.

Hi All
I am trying to experiment a memory management - allocate memory segments in
Kernel space (junk of memory segments using page allocation) so that
different user process can use/access it(read/write) using mmap.
For example,
I have 2 different user space process A,B etc. I have to allocate

has ISA mem map hole (640k -to 1MB). From 1st BM till 896MB is occupied
by the kernel. Then user space will be

Hi,
Recently i've started with development of kernel module, which uses
existing block devices/partitions as backend and represents itself as
scsi disk.
i've found good start point - scsi_debug module which is in official
