Subject: [SCSI] iscsi: fix 2.6.19 data digest calculation bug
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c959e1c2a475e0ad0d24eff200de9b6dcb3710c6;p=linux-beck.git

[SCSI] iscsi: fix 2.6.19 data digest calculation bug

The transition from crypto_digest_*() to  the crypto_hash_*() family
introduced a bug into the data digest calculation: crypto_hash_update() is
called with the number of S/G elements instead of the S/G lists data size.
