[Qemu-devel] [PATCH v3 3/5] raw-posix: DPRINTF instead of DEBUG_BLOCK_PRINT

[Dimitris Aragiorgis]

Building the QEMU tools fails if we #define DEBUG_BLOCK inside
block/raw-posix.c. Here instead of adding qemu-log.o in block-obj-y
so that DEBUG_BLOCK_PRINT can be used, we substitute the latter with
a simple DPRINTF() (that does not cause bit-rot).
