trasz 2009-02-05 08:46:18 UTC FreeBSD src repository Modified files: sys/kern vfs_syscalls.c Log: SVN rev 188141 on 2009-02-05 08:46:18Z by trasz In some situations, mnt_lockref could go negative due to vfs_unbusy() being called without calling vfs_busy() first. This made umount(8) hang waiting for mnt_lockref to become zero, which would never happen.
