Hi,

The patch series implement file descriptor reclaim support in
VirtFS server. VirtFS qemu server track open file descriptor
on the client using an open fid. This result in server returning
EMFILE error even though on the client side the process have not
reached maximum open file limit.

To fix this we reclaim file descriptor on the server when we
reach high watermark.

The following changes since commit 56a7a874e962e28522857fbf72eaefb1a07e2001:

  Merge remote-tracking branch 'stefanha/trivial-patches' into staging (2011-08-25 07:50:07 -0500)
