On the block device driver i am writing :
I have a bio such that the bvec has a page with bvec->bv_len = 4096.
I want to create two bios with this bvec such that
bio1 --> contains 7 sectors(len1)
bio2 --> contiains 1 sector(len2)
I tried using bio_add_page as follows :
bio_add_page(bio1, bvec->bv_page, len1, bvec->bv_offset)
bio_add_page(bio2, bvec->bv_page, len2, bvec->bv_offset + len1)
But my second 'bio_add_page' returns 0 and not len2 indicating that
there is something wrong.
Is there some other way to do this???
