Milan Broz 91e1062592 dm crypt: use bio_add_page ... Fix possible max_phys_segments violation in cloned dm-crypt bio. In write operation dm-crypt needs to allocate new bio request and run crypto operation on this clone. Cloned request has always the same size, but number of physical segments can be increased and violate max_phys_segments restriction. This can lead to data corruption and serious hardware malfunction. This was observed when using XFS over dm-crypt and at least two HBA controller drivers (arcmsr, cciss) recently. Fix it by using bio_add_page() call (which tests for other restrictions too) instead of constructing own biovec. All versions of dm-crypt are affected by this bug.
