Hi all,
In kernel 2.4.18, in the struct "buffer_head", there was a field
"struct inode * b_inode", which to my knowledge was used to indiacate
the inode to which that buffer head is assigned. In kernel 2.4.21 this
field is removed. Hence I am getting kind of confused in basic
concepts, like:
- Inside a page, if there are 4 buffers, can they be callocated to
different files?
- if yes, how do I come to know which buffer is assigned to which
file (in kernel 2.4.21)
- or entire page is dedicated to a single file?
Thanks and regards,
Vin
