[dpdk-dev] [PATCHv4 1/5] buildtools: Add tool to check EXPERIMENTAL api exports

[Thomas Monjalon]

Hi Neil,

Sorry for the very late review.
I thought review had been done by others but it seems not.
Please find my comments below.

When adding a new file, you must reference it in MAINTAINERS.
Please add it in the section "ABI versioning".

I think the file name should include the word "check".
What about check-experimental-syms.sh ?

You must insert a SPDX license and copyright here.

Why checking for not being a directory?
I guess you could check being a readable file (-r)?
Should it return an error?

exit 0 is useless at the end of a script.
