From ee29d6adefcca7e76abb124183814ed3acc74fac Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Thu, 4 May 2017 12:37:45 -0500 Subject: block: Simplify BDRV_BLOCK_RAW recursion Since we are already in coroutine context during the body of bdrv_co_get_block_status(), we can shave off a few layers of wrappers when recursing to query the protocol when a format driver returned BDRV_BLOCK_RAW. Note that we are already using the correct recursion later on in the same function, when probing whether the protocol layer is sparse in order to find out if we can add BDRV_BLOCK_ZERO to an existing BDRV_BLOCK_DATA|BDRV_BLOCK_OFFSET_VALID.
