[Qemu-devel] [PATCH v3 01/10] block: Prefix file driver trace points with "file_"

[Fam Zheng <famz@redhat.com>]

With in one module, trace points usually have a common prefix named
after the module name. paio_submit and paio_submit_co are the only two
trace points so far in the two file protocol drivers. As we are adding
more, having a common prefix here is better so that trace points can be
enabled with a glob. Rename them.
