Hi...
I want to add my own bit (a #define PG_MYBIT)
similar to into the flags in task_struct as defined
in linux v2.4.4 in sched.h which is defined as:

unsigned long flag; /*per process flags */

I want a free #define where I can define the
process specific flag like PG_EXITING, PG_STARTING.

Similarly, I also want to add my own bit into the
flags in the _page struct_ wherein I can establish
the state of a particular page.

Using this my program wants to distinguish
between some privileged pages of a process
(privileged for my program which serves them..) from
other processes and pages.

Please tell me which #define can I use to do this
in both the structures.

Thanking you in advance,

Amber
