From 4e4cbee93d56137ebff722be022cae5f70ef84fb Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 3 Jun 2017 09:38:06 +0200 Subject: block: switch bios to blk_status_t Replace bi_error with a new bi_status to allow for a clear conversion. Note that device mapper overloaded bi_error with a private value, which we'll have to keep arround at least for now and thus propagate to a proper blk_status_t value.
