So if one inserts a USB drive with a GPT that doesn't match the media size, a resize is initiated, so gpart takes g_access(cp, 1, 1, 1) on the disk and holds it until the resize is accepted or rejected. The orphan path releases it, but the spoil path does not. So if the drive is ejected while the resize is in flight, we call spoil directly, without releasing the access. Since gpt_opened is not cleared for the spoil path, this causes several different process to hang in the open path waiting for the leaked access. Move the release into the wither function when gpt_opened is set, and remove the release elsewhere. Since all paths to destroy the geom pass through wither, this ensure that access is always released when we've taken the access for resize.

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.
