From e4ec5ad464e48ab8d978b4dd8aacd05c1c4a87cc Mon Sep 17 00:00:00 2001 From: Pavel Dovgalyuk Date: Tue, 17 Sep 2019 14:58:19 +0300 Subject: replay: add BH oneshot event for block layer Replay is capable of recording normal BH events, but sometimes there are single use callbacks scheduled with aio_bh_schedule_oneshot function. This patch enables recording and replaying such callbacks. Block layer uses these events for calling the completion function. Replaying these calls makes the execution deterministic.
