From 9fef41f25d60d3cb22ee81d5d92cdea99a1b35ea Mon Sep 17 00:00:00 2001 From: "Ahmed S. Darwish" Date: Thu, 26 Nov 2020 14:29:43 +0100 Subject: [PATCH] scsi: target: tcm_qla2xxx: Remove BUG_ON(in_interrupt()) tcm_qla2xxx_free_session() has a BUG_ON(in_interrupt()). While in_interrupt() is ill-defined and does not provide what the name suggests, it is not needed here: the function is always invoked from workqueue context through "struct qla_tgt_func_tmpl" ->free_session() hook it is bound to. The function also calls wait_event_timeout() down the chain, which already has a might_sleep(). Remove the in_interrupt() check.
