[Qemu-devel] [PATCH for 4.2 v5 01/15] linux user: Add support for FDFLUSH ioctl |
Date: |
Thu, 1 Aug 2019 14:21:02 +0200 |
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.
