Subject: [PULL 16/26] include: Move qemu_madvise() and related #defines to new qemu/madvise.h
Date: Mon, 21 Feb 2022 09:27:50 +0000	[thread overview]
Message-ID: <20220221092800.404870-17-peter.maydell@linaro.org> (raw)
In-Reply-To: <20220221092800.404870-1-peter.maydell@linaro.org>

The function qemu_madvise() and the QEMU_MADV_* constants associated
with it are used in only 10 files.  Move them out of osdep.h to a new
qemu/madvise.h header that is included where it is needed.
