hi
For past few days i have been working in the kernel page cache
datastructures for some optimizations....and while using them i
came across the necessity to have the size of those files which are
put in cache. I thought it would be easy, for from 'address_space'
datastructure i could access 'inode' and then 'i_size'.
but the PROBLEM is that while accessing this field during the fetching
of any file to page cache this field value starts from 0 and goes on
increasing.. (as a matter inc by multiple of page size) . why is it so??
i thought we could get a file size from the field i_size...
So my question is ..is there any way to get file size of any file during
kernel booting....and also if possible can any one explain the above
behaviour???
