From 1d39c7098bbfa6862cb96066c4f8f6735ea397c5 Mon Sep 17 00:00:00 2001 From: Alberto Faria Date: Thu, 9 Jun 2022 16:27:41 +0100 Subject: block: Implement bdrv_{pread,pwrite,pwrite_zeroes}() using generated_co_wrapper bdrv_{pread,pwrite}() now return -EIO instead of -EINVAL when 'bytes' is negative, making them consistent with bdrv_{preadv,pwritev}() and bdrv_co_{pread,pwrite,preadv,pwritev}(). bdrv_pwrite_zeroes() now also calls trace_bdrv_co_pwrite_zeroes() and clears the BDRV_REQ_MAY_UNMAP flag when appropriate, which it didn't previously.
