-Subject: [PATCH 08/50] printk: ringbuffer: Cleanup reader terminology
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.7/older/patches-6.7-rt6.tar.xz
-
-With the lockless ringbuffer, it is allowed that multiple
-CPUs/contexts write simultaneously into the buffer. This creates
-an ambiguity as some writers will finalize sooner.
-
-The documentation for the prb_read functions is not clear as it
-refers to "not yet written" and "no data available". Clarify the
-return values and language to be in terms of the reader: records
-available for reading.
