Subject: [GIT PULL] printk for 5.2
Linus,
please pull the latest printk changes from
git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk tags/printk-for-5.2
==================
- Allow to reset state of printk_once() calls.
- Prevent crashes when dereferencing invalid pointers in vsprintf().
Only first byte is checked for simplicity.
- Make vsprintf warnings consistent and inlined.
- Treewide conversion of obsolete %pf, %pF to %ps, %pF printf modifiers.
- Some clean up of vsprintf and test_printf code.
===================
The %pf, %pF conversion caused about 5 merge conflicts in linux-next.
An alternative is to remove the merge of 'for-5.2-pf-removal' branch
and run the following:
git grep -l '%p[fF]' | grep -v '^\(tools\|Documentation\)/' | \
while read i; do perl -i -pe 's/%pf/%ps/g; s/%pF/%pS/g;' $i; done
Feel free to ask me to prepare pull request without the Sakari's patch.
