| |
Hi Linus,
please pull the latest printk changes from
git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux.git tags/printk-for-5.18
==========================================
- Make %pK behave the same as %p for kptr_restrict == 0 also with no_hash_pointers parameter.
- Ignore the default console in the device tree also when console=null or console="" is used on the command line.
- Document console=null and console="" behavior.
- Prevent a deadlock and a livelock caused by console_lock in panic().
- Make console_lock available for panicking CPU.
- Fast query for the next to-be-used sequence number.
- Use the expected return values in printk.devkmsg __setup handler.
- Use the correct atomic operations in wake_up_klogd() irq_work handler.
- Avoid possible unaligned access when handling %4cc printing format.
---------------------------------------------------------------- Andre Kalb (1): printk: Set console_set_on_cmdline=1 when __add_preferred_console() is called with user_specified == true
Andy Shevchenko (2): vsprintf: Fix potential unaligned access vsprintf: Move space out of string literals in fourcc_string()
Christophe Leroy (1): vsprintf: Fix %pK with kptr_restrict == 0
Jiapeng Chong (1): printk: make suppress_panic_printk static
John Ogness (1): printk: use atomic updates for klogd work
Petr Mladek (4): printk: ringbuffer: Improve prb_next_seq() performance Merge branch 'for-5.18-vsprintf-fourcc-fixup' into for-linus Merge branch 'for-5.18-panic-deadlocks' into for-linus Merge branch 'rework/fast-next-seq' into for-linus
Randy Dunlap (2): Docs: printk: add 'console=null|""' to admin/kernel-parameters printk: fix return value of printk.devkmsg __setup handler
Stephen Brennan (4): printk: Add panic_in_progress helper printk: disable optimistic spin during panic printk: Avoid livelock with heavy printk during panic printk: Drop console_sem during panic
