const struct file_operations struct definition

[santi mondal]

Hi All,

I was trying to build a kernel module to block all the writes
happening to a particular disk/mount point (multiple disk/mount points
at the same time). To achieve this I tried to replace the
file_operations->write function pointer. Since it is defined as
"const", replacing it is not poissible. Is there any way outs to get
the control in the filesystem's write funtion ?

It would be of great help if anybody could throw some ideas.
