[Qemu-devel] [PATCH V2 2/7] monitor: discard global variable *mon_cmds

[Wenchao Xia <xiawenc@linux.vnet.ibm.com>]

New member *cmd_table is added in structure Monitor to avoid direct usage of
*mon_cmds. Now monitor have an associated command table, when global variable
*info_cmds is also discarded, structure Monitor would gain full control about
how to deal with user input.
