From e124c5afaf88c4b25dcfcaf7d16e3a6f24b850c0 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 13 Nov 2020 15:19:10 +0100 Subject: [PATCH] dm table: Remove BUG_ON(in_interrupt()) [ Upstream commit e7b624183d921b49ef0a96329f21647d38865ee9 ] The BUG_ON(in_interrupt()) in dm_table_event() is a historic leftover from a rework of the dm table code which changed the calling context. Issuing a BUG for a wrong calling context is frowned upon and in_interrupt() is deprecated and only covering parts of the wrong contexts. The sanity check for the context is covered by CONFIG_DEBUG_ATOMIC_SLEEP and other debug facilities already.
