[Qemu-block] [PATCH v4 06/39] qcow2: Remove BDS parameter from qcow2_cache_entry_mark_dirty() |
Date: |
Mon, 5 Feb 2018 16:33:06 +0200 |
This function was only using the BlockDriverState parameter to pass it
to qcow2_cache_get_table_idx(). This is no longer necessary so this
parameter can be removed.
