Hi Marcos,
A memory bank for RAM is just an individual addressable array on a
memory board. The addressing of the bank is managed by the memory
controller.

Hi,
If you want to see the SCSI mid-layer implementation check out:
drivers/scsi/scsi.c
If you are curious about the SCSI commands sent to a SCSI disk you can
look at:
drivers/scsi/sd.c
SCSI tape:
drivers/scsi/st.c
SCSI optical media (CDs/DVDs)
drivers/scsi/sr.c
SCSI enclosures

Hemanth,
You can set a hard memory limit with the mem= kernel parameter.

That is most likely due to the filesystem cache. Try running iostat
and checking the block device statistics for the device you froze!

Hi,
You are missing USB support in your configuration. Please check your
configuration again and make sure you enable all of the modules you
need!
# CONFIG_USB_SUPPORT is not set

Can you share your .config file to the mailing list? It is located in
the kernel base directory e.g. /usr/src/linux-2.6.26 (or wherever the
kernel you built is located)

You can stack a driver on top of another to enhance functionality. For
an example check the Linux RAID and LVM implementations. In general
you don't need filter drivers because you can modify the Linux kernel
to add functionality, where in Windows you generally cannot.

Yes it is do-able you can actually use the zImage header to bootstrap
the kernel. You can modify linux/arch//boot/compressed/

That is true [ I missed that tiny detail ;-) ] in either case you
would need create a custom kernel with the function exported with
EXPORT_SYMBOL().
Why do you need to obtain a list of available filesystems from a
driver? Shouldn't you handle this in an application instead?
Best Regards,
If you are using kernel 2.6.24 or below you can specify the prototype:
extern int get_filesystem_list(char *);
It does not look like this function was intended for general use, so
be careful.

The ext filesystem supports extended attributes, which you can use to
store a pointer to another file (which could be your other file stream
if you like). The application can read the extended attribute which
contains the information about where the fork is located and process
