Do you have a list of the PRs that this affects and/or resolves? I'm curious, specifically, about kern/84589. I believe it may be related to snapshots in some way, but I don't know. I'm not going to be able to test the patch on these servers, unfortunately, as they're fully in production now. The servers are stable now with background_fsck=3D"NO", but "YES" is still the default (last I checked). FWIW: the deadlock in 84589 doesn't involve quotas, as there were no quotas enabled in the kernel. The URLs referenced in the PR are no longer valid (they were never clicked) but I can produce them if necessary. Also: http://www.freebsd.org/releases/6.1R/todo.html The todo page mentions deadlocks but doesn't link to any specific PRs/threads that discuss them. Are these fixed with this MFC?
