Linus,
please pull the latest printk changes from
git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux.git tags/printk-for-5.12
==============================
- New "no_hash_pointers" kernel parameter causes that %p shows raw
pointer values instead of hashed ones. It is intended only for
debugging purposes. Misuse is prevented by a fat warning message
that is inspired by trace_printk().
- Prevent a possible deadlock when flushing printk_safe buffers during
panic().
- Fix performance regression caused by the lockless printk ringbuffer.
It was visible with huge log buffer and long messages.
- Documentation fix-up.
----------------------------------------------------------------
John Ogness (1):
printk: avoid prb_first_valid_seq() where possible
Lukas Bulwahn (1):
printk: rectify kernel-doc for prb_rec_init_wr()
Muchun Song (1):
printk: fix deadlock when kernel panic
Petr Mladek (2):
Merge branch 'for-5.12-no_hash_pointers' into for-linus
Merge branch 'printk-rework' into for-linus
Timur Tabi (3):
lib: use KSTM_MODULE_GLOBALS macro in kselftest drivers
kselftest: add support for skipped tests
lib/vsprintf: no_hash_pointers prints all addresses as unhashed
