Hi all

   task_struct (process descripter) is used for saving "context of
process" and contain all detail information about them.Also Kernel
Stack is there for further information .
But What is the Need of Task State Segment(TSS).. for Linux.I think it
is duplicate information???

   For Every Context switch ,state of TSS changed???
Thanx in advance and sorry for New bee question....
