Re: [Xen-devel] [PATCH] Make ACPI DMAR parsing more robust

[Keir Fraser <keir.fraser@xxxxxxxxxxxxx>]

Regarding the table length sanity check -- depth is set to the number of
acp_pci_path structures in the table. But then we only follow the path to
depth-1. Is that correct?

Also I changed the test to '--depth >= 0' which is equivalent and a bit
easier to read imo.
