[Qemu-devel] [PATCH v6 4/8] linux user: Add support for FDFLUSH ioctl |
Date: |

From: Yunqiang Su <address@hidden>
FDFLUSH is used for flushing buffers of floppy drives. Support in
QEMU is needed because some of Debian packages use this ioctl while
running post-build tests. One such example is 'tar' package.
