[dpdk-dev] [PATCH v2 05/19] vhost: rename device fh to vid
Yuanhan Liu
yuanhan.liu at linux.intel.com
Fri May 13 07:24:57 CEST 2016
I failed to figure out what does "fh" mean here for a long while.
The only guess I could have had is "file handle". So, you get the
point that it's not well named.
I then figured it out that "fh" is derived from the fuse lib, and
my above guess is right. However, device_fh represents a virtio
net device ID. Therefore, here I rename it to vid (Virtio-net device
ID, or Vhost device ID; choose one you prefer) to make it easier for
understanding.
This name (vid) then will be considered to the only interface to
applications. That's another reason to do the rename: it's our
interface, make it more understandable.
