| H A D | block.h | diff 4333bb71405f58a8dc8d3255feb3ca5960b0daf8 Wed Sep 04 12:00:29 CDT 2013 Paolo Bonzini <pbonzini@redhat.com> block: define get_block_status return value
Define the return value of get_block_status. Bits 0, 1, 2 and 9-62
are valid; bit 63 (the sign bit) is reserved for errors. Bits 3-8
are left for future extensions.
The return code is compatible with the old is_allocated API: if a driver
only returns 0 or 1 (aka BDRV_BLOCK_DATA) like is_allocated used to,
clients of is_allocated will not have any change in behavior. Still,
we will return more precise information in the next patches and the
new definition of bdrv_is_allocated is already prepared for this.
