To quote from a comment above vput_final: <quote> * XXX Some filesystems pass in an exclusively locked vnode and strongly depend * on the lock being held all the way until VOP_INACTIVE. This in particular * happens with UFS which adds half-constructed vnodes to the hash, where they * can be found by other code. </quote> As is there is no mechanism which allows filesystems to denote that a vnode is fully initialized, consequently problems like the above are only found the hard way(tm). Add rudimentary support for state transitions, which in particular allow to assert the vnode is not legally unlocked until its fate is decided (either construction finishes or vgone is called to abort it). The new field lands in a 1-byte hole, thus it does not grow the struct.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
