From 86ec403638453fc068f4aaae684c26170d20bc44 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Fri, 20 Oct 2023 13:34:08 +0200 Subject: [PATCH] quota: Remove BUG_ON from dqget() [ Upstream commit 249f374eb9b6b969c64212dd860cc1439674c4a8 ] dqget() checks whether dquot->dq_sb is set when returning it using BUG_ON. Firstly this doesn't work as an invalidation check for quite some time (we release dquot with dq_sb set these days), secondly using BUG_ON is quite harsh. Use WARN_ON_ONCE and check whether dquot is still hashed instead.
