hannken a3a898ff0f Add the gating of system calls that cause modifications to the underlying ...

file system.
The function vfs_write_suspend stops all new write operations to a file
system, allows any file system modifying system calls already in progress
to complete, then sync's the file system to disk and returns. The
function vfs_write_resume allows the suspended write operations to
complete.

From FreeBSD with slight modifications.
