From de7056a3f95e85aa6bba30ad4b37a8dbc2b072ab Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Tue, 24 Apr 2018 14:25:02 -0500 Subject: file-win32: Switch to byte-based callbacks We are gradually moving away from sector-based interfaces, towards byte-based. Make the change for the last few sector-based callbacks in the file-win32 driver. Note that the driver was already using byte-based calls for performing actual I/O, so this just gets rid of a round trip of scaling; however, as I don't know if Windows is tolerant of non-sector AIO operations, I went with the conservative approach of modifying .bdrv_refresh_limits to override the block layer defaults back to the pre-patch value of 512.
