changing hostcache dynamically, is handled here.

qemu command option 'hostcache' added to -drive for block devices.
While starting a VM from qemu commandline, this option can be used
for setting host cache usage for block data access. 'cache=xx'
overrides 'hostcache=yy' when specified simultaneously.
New error classes defined for file reopen failure and data
sync error

Currently cache setting of a block device cannot be changed
without restarting a running VM. Following patchset is for
enabling dynamic change of cache setting for block devices
through qemu monitor. Code changes are based on patches
from Christoph Hellwig and Prerna Saxena.

qemu command option 'hostcache' added to -drive for block devices.
While starting a VM from qemu commandline, this option can be used
for setting host cache usage for block data access. Simultaneous
use of 'hostcache' and 'cache' options not allowed.
New command "block_set_hostcache" added for dynamically changing
host pagecache setting of a block device.
Usage:
block_set_hostcache
= block device
= on/off
Example:
(qemu) block_set_hostcache ide0-hd0 off
