Hi all, I'm running again into problems related to referencing and locking of vnodes. This time it's in nresolve on vrele(vp) where vp is a newly allocated vnode (or recycled if possible). vrele() causes a page fault when the vnode is a device node. It doesn't cause any problems as far as I've seen with any other type (directory, symlink). I can't quite understand what could be causing this.
devfs_nresolve() can be found in devfs_vnops.c and devfs_allocv() can be found in devfs_core.c. If anyone can offer me his insight on what could be causing this problem I'd appreciate it. My current code is at: http://gitweb.dragonflybsd.org/~alexh/dragonfly.git/tree/aae02cbf0350ca50b64b381042f7eea01a44c1bc:/sys/vfs/devfs About devfs status: While I'm still dealing with the above panic and the code isn't cleaned up and there might still be some locking issues, devfs already creates devices dynamically, provides an automated cleanup for empty directories and aliases (links) to devices that have been removed, and allows to create symlinks. Right now I'm working on getting the interface to the device itself to work (hence the above panic which occurs doing a cat /mnt/null > test or for that matter any other device node). Thank you in advance, Alex Hornung
