Subject: block: Drop bdrv_parent_cb_...() from bdrv_close()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6b574e09b34a10dbf8d9fb58aeaad77493826b97;p=qemu.git

block: Drop bdrv_parent_cb_...() from bdrv_close()

bdrv_close() now asserts that the BDS's refcount is 0, therefore it
cannot have any parents and the bdrv_parent_cb_change_media() call is a
no-op.
