[Qemu-devel] [PATCH] raw-posix: inline paio_ioctl into hdev_aio_ioctl

[Qemu-devel] [PATCH] raw-posix: inline paio_ioctl into hdev_aio_ioctl

[Paolo Bonzini]

clang now warns about an unused function:
  CC    block/raw-posix.o
block/raw-posix.c:707:26: warning: unused function paio_ioctl
[-Wunused-function]
static BlockDriverAIOCB *paio_ioctl(BlockDriverState *bs, int fd,
                         ^
1 warning generated.

because the only use of paio_ioctl() is inside a #if defined(__linux__)
guard and it is static now.
