[v2,2/4] eal: modify device event callback process func
Checks
Commit Message
This patch modify the device event callback process function name to be
more explicit, change the variable to be const and exposure the API out
from private eal. The bus drivers and eal device would directly use this
API to process device event callback.
Signed-off-by: Jeff Guo <jia.guo@intel.com>
---
v2->v1:
change the rte_dev_event_callback_prcess from internal to external api
for bus or app usage.

Sorry, but from the description it is unclear what has changed to
make it necessary.

Consider to avoid split of log message to simplify search using grep.

the reason is that not only eal device help will use the callback, but
also vfio bus will use
the callback to handle hot-unplug. So exposure these API to let vfio
call it. I will add detail
more at next version if need.

i think i got your point, but the 80 limitation a line and the clearly
meaning of the log should be the 1 prior to be considerate,
right? It should be considerate but it is inevitable.

It is OK to have line longer than 80 symbols in this case. As far as I
know checkpatches.sh accepts it and does not generate any errors/warnings.
