Subject: [PULL 3/8] 9pfs: simplify blksize_to_iounit()
Date: Wed, 27 Oct 2021 15:18:33 +0200 [thread overview]
Message-ID: <04a7f9e55e0930b87805f7c97851eea4610e78fc.1635340713.git.qemu_oss@crudebyte.com> (raw)
In-Reply-To: <cover.1635340713.git.qemu_oss@crudebyte.com>
Use QEMU_ALIGN_DOWN() macro to reduce code and to make it
more human readable.
