From e23947bd76f00701f9407af23e671f4da96f5f25 Mon Sep 17 00:00:00 2001 From: Dmitry Monakhov Date: Thu, 29 Jun 2017 11:31:11 -0700 Subject: bio-integrity: fold bio_integrity_enabled to bio_integrity_prep Currently all integrity prep hooks are open-coded, and if prepare fails we ignore it's code and fail bio with EIO. Let's return real error to upper layer, so later caller may react accordingly. In fact no one want to use bio_integrity_prep() w/o bio_integrity_enabled, so it is reasonable to fold it in to one function. Signed-off-by: Dmitry Monakhov Reviewed-by: Martin K.
