I want to see Kirk McKusick's softupdates go into the tree soon. This is a very significant step in the development of FreeBSD. We will get higher performance ffs without integrity compromises. http://www.ece.cmu.edu/~ganger/papers/CSE-TR-254-95/ I think these changes in themselves warrant a 3.0 jump. Giant lock or subsystem coarse lock SMP and softupdates is probably a good target. When softupdates are are applied and have stabilized a bit, I'll submit the first set of VFS_VRELE patches for vop_create, vop_mknod, and vop_symlink. This is mostly just grunt work but is a fundamental first step in making the stacking layers work. It will clean up ugly hacks like WILLRELE and make some things a lot easier to get working for file systems like devfs. It will also prevent VT_TFS-like hacks that third parties must sometime resort to forcing on us because we didn't have a proper VFS interface to allow them to manage their own vnodes.
