John Ogness ac7d7844c6 printk: Wait for all reserved records with pr_flush() ... Currently pr_flush() will only wait for records that were available to readers at the time of the call (using prb_next_seq()). But there may be more records (non-finalized) that have following finalized records. pr_flush() should wait for these to print as well. Particularly because any trailing finalized records may be the messages that the calling context wants to ensure are printed. Add a new ringbuffer function prb_next_reserve_seq() to return the sequence number following the most recently reserved record. This guarantees that pr_flush() will wait until all current printk() messages (completed or in progress) have been printed. Fixes: 3b604ca812 ("printk: add pr_flush()") Signed-off-by: John Ogness <john.ogness@linutronix.de> Reviewed-by: Petr Mladek <pmladek@suse.com> Link: https://lore.kernel.org/r/20240207134103.1357162-10-john.ogness@linutronix.de Signed-off-by: Petr Mladek <pmladek@suse.com>		2024-02-07 17:23:18 +01:00
