Subject: Let FSes exit themselves upon system shutdown
X-Git-Tag: v3.2.0~331
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/Bv9ARM.ch10.html?a=commitdiff_plain;h=78183bddffc53b6ee8f8bfaeeba11b97a841ee3f;p=minix.git

Let FSes exit themselves upon system shutdown

During shutdown all processes are semi-exited and FSes are unmounted.
This semi-exit causes trouble for FUSE mounts as they still need access
to file descriptors and working directory in order to unmount.
