Hi,
I have a doubt on how ext3 handles read in this specific case.
Assume that a page is written to the journal but not yet updated to its actual location and before updating the actual copy the page gets invalidated. Now if a read comes to the same data, which block will be read: the journal copy or the actual copy ?
First of all, will this situation ever occur ? The page will be marked dirty until it is written to its actual location so it may never get invalidated until it is written to the actual location!
I appreciate your help.
Since I'm not subscribed to this list, could you please CC your answers to my personal mailid.
Thanks. Vijayan
