[uml-devel] hostfs leaks file descriptors

[Ingo v. L. <in...@gm...>]

Hi there,

when hostfs is used as the UML's root filesystem its file descriptors 
aren't closed when the kernel is rebooted. Subsequently, after a couple 
of reboots the guest will reach the maximum number of allowed file 
descriptors (usually 1024) and fail to open any more files.

I tried to fix the problem myself, see patch. It works for me, but I'm 
not sure if it's the correct solution.

Cheers,
Ingo
