From d24de76af836260a99ca2ba281a937bd5bc55591 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 3 Jun 2020 07:14:43 +0200 Subject: block: remove the error argument to the block_bio_complete tracepoint The status can be trivially derived from the bio itself. That also avoid callers like NVMe to incorrectly pass a blk_status_t instead of the errno, and the overhead of translating the blk_status_t to the errno in the I/O completion fast path when no tracing is enabled.
