From: Robert Watson To: phk@FreeBSD.org Cc: freebsd-gnats-submit@FreeBSD.org, Sheldon Hearn Subject: Re: kern/20804: deadlocking when using vnode disk file and quotas Date: Thu, 24 Aug 2000 09:39:17 -0400 (EDT) Poul-Henning, Do you have a chance to look at this bug, which was raised on -fs recently? It has to do, I believe, with a recursive lock/deadlock issue relating to the md device and the UFS quota implementation, presumably a lock ordering issue relating to the md device vnode lock and the vnode lock for the quota data file on that file system. I haven't had a chance to look much further, and apparently it mostly manifests in jail (I'm not sure I understand why that might be the case -- possibly having to do with the starting point (root) for recursive name lookups with lock requests).

Robert, do you want this PR for yourself, or was it your intention to have it assigned to phk? Ciao, Sheldon.
