Had posted this one to freebsd-fs but there is apparently not too much going on. So, am retrying it here. I am working on stackable filesystems using 5.3-STABLE and figured that there are still deadlock problems when using the nullfs template on a busy, stressed machine. >From what I have experienced, apparently the deadlock occurs when trying to get a new node while it's being recycled. What I have seen in the VFS code of the CURRENT branch looks very promising (VI_DOOMED instead of VI_XLOCK!), but as I have no clue when new VFS stuff will be in a solid state, I wanted to ask if the problem is at all solveable with the VFS concept under 5.3 and if so, how. If it is not solveable (which is my personal guess) would someone mind giving me a hint on dependencies when I would only like to use as much stuff from CURRENT to move to new VFS concept (with all the ostentatious risks)? Thanks very much! GuntherReceived on Fri Apr 15 2005 - 10:02:24 UTC
