The following patchset introduces monitor commands: 1. set_cache DEVICE CACHE-SETTING Change cache settings for block device, DEVICE, through the monitor. (Available options : 'none', 'writeback', 'writethrough') Eg, (qemu)set_cache ide0-hd0 none -> Changes cache setting for ide0-hd0 to 'none'
2. info block Now extended to display cache settings for available block devices. TODOS : ------- 1. Support 'unsafe' cache mode. 2. Display current cache setting for device, if the CACHE-SETTING option is not supplied by the user. Eg, (qemu)set_cache ide0-hd0 presently errors out. Ideally, it should display current cache setting for the given device ide0-hd0 -- Prerna Saxena Linux Technology Centre, IBM Systems and Technology Lab, Bangalore, India
