Hi,
Here is the 6th version of patches to fix vsnprintf().
- Fix to limit the size of width and precision.
- Warn if the return size is over INT_MAX.
Previous version is here;
https://lore.kernel.org/all/177444525139.185641.12184379647176430297.stgit@devnote2/
This version just makes function header and WARN_ONCE() to one line[1/2].
No functional change.
Thank you,
---
