regarding page flags.....

[<ashok.shanmugam@xxxxxxxxx>]

 

Hi ppl,

 

   I have a doubt on using the flags of the structure page.

 

   Is the 21st bit on the member page->flags  used ?   I saw from the file linux/page-flags.h that only 0-19 and 31-23 bit no's are used. So in that case can i use the 21st bit(bit no 20) for my purpose confidently.

 

Thanks
