[Xen-devel] [PATCH] qemu-xen: add IDE SEEK_STAT flag to all non-error cases except sleep requests
Add SEEK_STAT in all non-error cases except sleep requests, since our
seek times are virtually 0. Although this flag is deprecated by newer
ATA standards, Linux at least checks it for CD drives, and would timeout
in some cases if we do not set it.
