Message-ID: <56797413.3090904@akamai.com> Date: Tue, 22 Dec 2015 11:02:27 -0500 From: Jason Baron <jbaron@...mai.com> To: Greg KH <gregkh@...uxfoundation.org>, linux-kernel@...r.kernel.org, Andrew Morton <akpm@...ux-foundation.org>, torvalds@...ux-foundation.org, stable@...r.kernel.org Cc: lwn@....net, Jiri Slaby <jslaby@...e.cz>, Al Viro <viro@...iv.linux.org.uk>, mika.westerberg@...ux.intel.com Subject: Re: Linux 3.14.58 Hi, We've noticed livelocks in shrink_dentry_list() very similar to this report on stable 3.14.56: http://lkml.iu.edu/hypermail/linux/kernel/1405.3/00470.html It appears that the patches that introduced this issue came into 3.14.51 in August with the same set of patches mentioned in the referenced report. We unfortunately haven't narrowed down a reproducer, so I can't bisect the issue, but 3.14.50 did not appear to have the issue. Upstream merge commit - 6f6111e4a73d0f6370eb8be4f8e4523210b6a67d (Pull vfs dcache livelock fix from Al Viro) brought in a series to address this issue. So that may be needed here as well...
