From 546881aea9787ed5c626ac99ab80158ea9ae0515 Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Sun, 24 May 2009 20:04:00 +0300 Subject: [SCSI] libosd: Let _osd_req_finalize_data_integrity receive number of out_bytes _osd_req_finalize_data_integrity was trying to deduce the number of out_bytes from passed osd_request->out.bio. This is wrong when the bio is chained. The caller of _osd_req_finalize_data_integrity has more ready available information and should just pass it. Also in the light of future support for CDB-continuation segment this is a better solution.
