# Merge: 573de2a6e844 0f46c78391e1
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'printk-for-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk
#     
#     Pull printk updates from Petr Mladek:
#     
#      - Allow state reset of printk_once() calls.
#     
#      - Prevent crashes when dereferencing invalid pointers in vsprintf().
#        Only the 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.
#     
#     * tag 'printk-for-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk:
#       lib/vsprintf: Make function pointer_string static
#       vsprintf: Limit the length of inlined error messages
#       vsprintf: Avoid confusion between invalid address and value
#       vsprintf: Prevent crash when dereferencing invalid pointers
#       vsprintf: Consolidate handling of unknown pointer specifiers
#       vsprintf: Factor out %pO handler as kobject_string()
#       vsprintf: Factor out %pV handler as va_format()
#       vsprintf: Factor out %p[iI] handler as ip_addr_string()
#       vsprintf: Do not check address of well-known strings
#       vsprintf: Consistent %pK handling for kptr_restrict == 0
#       vsprintf: Shuffle restricted_pointer()
#       printk: Tie printk_once / printk_deferred_once into .data.once for reset
#       treewide: Switch printk users from %pf and %pF to %ps and %pS, respectively
#       lib/test_printf: Switch to bitmap_zalloc()
