[Qemu-devel] [PATCH for 4.2 v2 5/6] linux-user: Add support for FDSETEMSGTRESH, FDSETMAXERRS, and FDGETMAXERRS ioctls

[Aleksandar Markovic <aleksandar.markovic@rt-rk.com>]

From: Aleksandar Markovic <amarkovic@wavecomp.com>

FDSETEMSGTRESH, FDSETMAXERRS, and FDGETMAXERRS ioctls are commands
for controlling error reporting of a floppy drive.
