commit 407bf1c140f0757706c0b28604bcc90837d45ce2
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I90MN1
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=407bf1c140f0757706c0b28604bcc90837d45ce2

--------------------------------

[ Upstream commit f5ca233e ]

When the trace event enable and filter files are opened, increment the
trace array ref counter, otherwise they can be accessed when the trace
array is being deleted. The ref counter keeps the trace array from being
deleted while those files are opened.
