From 5b27b8ddbf37962fae8131cf595231b1be2c2b27 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Thu, 17 Feb 2022 23:40:16 -0500 Subject: [PATCH] dm: remove impossible BUG_ON in __send_empty_flush The flush_bio in question was just initialized to be empty, so there is no way bio_has_data() will return true. So remove stale BUG_ON().
