This function is only called from locations that return a -errno code, not just

Hi Neil
Looking up the references I see that some of the places looking at this
return value from the probe function
simply return their own -1 , and some return different enums relevant for
their context.
As they all look at !=0 or < 0 , but not all propagate the value they got
I used an explicit -1.
Do you have a specific enum in mind I should replace it with?

Don't split strings across lines. Checkpatch should complain about that.
It makes searching for error messages in source harder.
Instead do:
if (!*vfinfo) {
RTE_LOG(CRIT, PMD,
"%s(): Cannot allocate memory for private VF data\n",
__func__);
return -1;
}
Also why not use PMD_DRV_LOG() macro.

Thanks Stephen
I thought I handled all the split strings. Apparently checkpatches
overlooked it.
Will do a rescan on the entire patchset and fix those in v4.
Missed the separate log macro. Will change that as well

If returning default hugepage size of 0 is now a possibility, the
calling code needs to be able to handle that. Perhaps rewrite it as
returning int, and accepting pointer to pagesz? e.g.
static int get_default_hp_size(uint64_t *page_sz)
and fix the code below to handle error in reading default page size?

Local functions to this file,
changing from void to int are non-abi-breaking.
For handling the single function that cannot
change from void to int due to abi,
where this is the only place it is called in,
I added a state variable that is being checked
right after the call to this function.

This patch adds a new function that is called
per every checked patch,
and alerts for new instances of rte_panic/rte_exit.
The check excludes comments, and alerts in the case
of a positive balance between additions and removals.

This patchset needs to be rebased. There were a few changes that make
some of the patches unnecessary.
Changes in patch 7 and 9 were addressed in earlier memory hotplug

patch 12 as well.
