Revision df2a6f29
| ID | df2a6f29a5019707d69f6eeb30cf792841cae5aa |
block: keep bs->total_sectors up to date even for growable block devices
If a BlockDriverState is growable, after every write we need to
check if bs->total_sectors might have changed. With this change,
bdrv_getlength does not need anymore a system call.
