From bf5b16fa401633475d21d69c66532f5b29e8433d Mon Sep 17 00:00:00 2001 From: Alberto Faria Date: Tue, 5 Jul 2022 17:15:09 +0100 Subject: block: Make blk_{pread,pwrite}() return 0 on success They currently return the value of their 'bytes' parameter on success. Make them return 0 instead, for consistency with other I/O functions and in preparation to implement them using generated_co_wrapper. This also makes it clear that short reads/writes are not possible.
