[Xen-devel] [PATCH] Macro for checking insance amounts of data on the ring (Xen patch).

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

Hey,

This patch had been posted in the past but had a glaring issue that
Jan spotted. This version fixes it. Said macro is being used in the
xen-blkback to check whether the indexes are bogus and the ring
is overflowed.
