Date: Tue, 3 Oct 2017 10:38:25 +0800 From: Jia-Ju Bai <baijiaju1990@....com> To: viro@...iv.linux.org.uk Cc: linux-fsdevel@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [BUG] fs/dcache: might_sleep is called under a spinlock According to fs/dcache.c, might_sleep is called under a spinlock, and the function call path is: d_prune_aliases (acquire the spinlock) dput might_sleep This bug is found by my static analysis tool and my code review. A possible fix is to remove might_sleep in dput. Thanks, Jia-Ju Bai
