Hi, all
I want ask a question.
As we know, structure buffer_head has a member called b_state.
And this state could be defined by many flags.
The question is that, I want to know the relationship between BH_Uptodate
& BH_Dirty.
If a data is verified, the BH_Dirty will setup, and what about BH_Uptodate?
Under what circumstance the BH_Uptodate would be set up?
Thanks. :)
