Jason A. Harmening 0745d837c2 unionfs: prevent upperrootvp from being recycled during mount ... If upperrootvp is doomed by a concurrent unmount, unionfs_nodeget() may return without a reference or lock on it. unionfs_domount() must prevent the vnode from being recycled for use by a different file until it is finished with the vnode, namely once vfs_register_upper_from_vp() fails. Accomplish this by holding the reference returned by namei() a bit longer. Reviewed by: kib, markj Tested by: pho Differential Revision: https://reviews.freebsd.org/D39767		2023-05-07 18:30:43 -05:00
