My bisect ended here:

commit 8ed936b5671bfb33d89bc60bdcc7cf0470ba52fe
Author: Eric W. Biederman <ebiederman@...tter.com>

     vfs: Lazily remove mounts on unlinked files and directories.


I haven reverted it yet.



Eric,

Immediately after starting dosemu all files under mount point /usr are 
gone. When I play a old dos game for a while (binaries are under /home) 
even /bin/ls disappears. Al mounts are nfs, even /.

Could you look in to this and cc this to the relevant kernel mailinglist?
