[Xen-devel] [PATCH][RESEND] Reporting wrong status for non-existant files

[Glauber de Oliveira Costa <gcosta@xxxxxxxxxx>]

Hi,

The block scripts under tools/examples is not reporting the proper
information in the event of a non-exitent file being passed on, like in
"file:/nonexistant,hda,w".

The block script is reporting the file as non-writable, even if it does
not exists
