Re: [PATCH v2] selftests/tracing: Fix test_multiple_writes stall
From: Fushuai Wang <hidden>

Also in:
linux-kselftest, lkml
When /sys/kernel/tracing/buffer_size_kb is less than 12KB,
the test_multiple_writes test will stall and wait for more
input due to insufficient buffer space.
Check current buffer_size_kb value before the test. If it is
less than 12KB, it temporarily increase the buffer to 12KB,
and restore the original value after the tests are completed.
