Subject: [Qemu-devel] [PATCH v3 01/29] fdc: Move floppy geometry guessing back from block.c
Date: Tue, 10 Jul 2012 11:12:27 +0200 [thread overview]
Message-ID: <1341911575-7306-2-git-send-email-armbru@redhat.com> (raw)
In-Reply-To: <1341911575-7306-1-git-send-email-armbru@redhat.com>
Commit 5bbdbb46 moved it to block.c because "other geometry guessing
functions already reside in block.c". Device-specific functionality
should be kept in device code, not the block layer. Move it back.
Disk geometry guessing is still in block.c. To be moved out in a
later patch series.
Bonus: the floppy type used in pc_cmos_init() now obviously matches
the one in the FDrive. Before, we relied on
bdrv_get_floppy_geometry_hint() picking the same type both in
fd_revalidate() and in pc_cmos_init().
