...) / uuid_equal() > guid_is_null() / guid_equal() The is_null is useful and I bet we'll find other instances. I'm not sure _equals really adds much value over the existing _cmp helpers, but on the other hand they are so trivial that we might as well add them. The other thing XFS has is uuid_copy.

...wledge that the common use case for filesystems is to handle an opaque char[16] which most likely holds a uuid_be and you should provide 'neutral' helpers to satisfy this use case. The simplest would be to typedef uuid_t to struct uuid_be and to name 'neutral' helpers' uuid_cmp/uuid_copy(uuid_t *, uuid_t *), similar to my proposal. I think with this semantic change, our proposals can reach common grounds and satisfy a wider group of users (i.e. filesystem developers). Christoph also suggested a similar treatment to typedef guid_t to struct uuid_le. I don't know the use cases...

This is a Fedora Core 13 environment and I just noticed this as I update the xen-unstable tree: make -C libxl install make[3]: Entering directory `/home/konrad/ssd/xtt/xen-unstable/tools/libxl'' rm -f _libxl_paths.h.tmp.tmp; echo "SBINDIR=\"/usr/sbin\"" >> _libxl_paths.h.tmp.tmp; echo "BINDIR=\"/usr/bin\"" >> _libxl_paths.h.tmp.tmp;

This patch series introduces the VHD library. It is based on the blktap2 one, with changes coming from the blktap2.5 one. Signed-off-by: Thanos Makatos <thanos.makatos@citrix.com>

acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16 bytes. Instead we convert them to use uuid_le type. At the same time we convert current users. acpi_str_to_uuid() becomes useless after the conversion and it's safe to get rid of it. The conversion fixes a potential bug in int340x_thermal as well since we have to use memcmp() on binary data. Cc: Rafael J. Wysocki <rjw
