+Subject: ring-buffer: Fix wrong stat of cpu_buffer->read
+
+From: Zheng Yejian <zhengyejian1@huawei.com>
+
+[ Upstream commit 2d093282b0d4357373497f65db6a05eb0c28b7c8 ]
+
+When pages are removed in rb_remove_pages(), 'cpu_buffer->read' is set
+to 0 in order to make sure any read iterators reset themselves. However,
+this will mess 'entries' stating, see following steps:
+
+ # cd /sys/kernel/tracing/
+ # 1. Enlarge ring buffer prepare for later reducing:
+ # echo 20 > per_cpu/cpu0/buffer_size_kb
+ # 2. Write a log into ring buffer of cpu0:
+ # taskset -c 0 echo "hello1" > trace_marker
+ # 3. Read the log:
+ # cat per_cpu/cpu0/trace_pipe
+ <...>-332 [000] ..... 62.406844: tracing_mark_write: hello1
+ # 4. Stop reading and see the stats, now 0 entries, and 1 event readed:
+ # cat per_cpu/cpu0/stats
+ entries: 0
+ [...]
+ read events: 1
+ # 5. Reduce the ring buffer
+ # echo 7 > per_cpu/cpu0/buffer_size_kb
+ # 6. Now entries became unexpected 1 because actually no entries!!!
+ # cat per_cpu/cpu0/stats
+ entries: 1
+ [...]
+ read events: 0
+
+To fix it, introduce 'page_removed' field to count total removed pages
+since last reset, then use it to let read iterators reset themselves
+instead of changing the 'read' pointer.

+From: Zheng Yejian <zhengyejian1@huawei.com>

+
+Warning happened in trace_buffered_event_disable() at
+ WARN_ON_ONCE(!trace_buffered_event_ref)
+
+ Call Trace:
+ ? __warn+0xa5/0x1b0
+ ? trace_buffered_event_disable+0x189/0x1b0

+ ftrace_filter_write+0xe6/0x140
+ vfs_write+0x1c9/0x6f0
+ [...]
+
+The cause of the warning is in __ftrace_event_enable_disable(),
+trace_buffered_event_enable() was called once while
+trace_buffered_event_disable() was called twice.
+Reproduction script show as below, for analysis, see the comments:
+ ```
+ #!/bin/bash
+
+ cd /sys/kernel/tracing/
+
+ # 1. Register a 'disable_event' command, then:
+ # 1) SOFT_DISABLED_BIT was set;
+ # 2) trace_buffered_event_enable() was called first time;
+ echo 'cmdline_proc_show:disable_event:initcall:initcall_finish' > \
+ set_ftrace_filter
+
+ # 2. Enable the event registered, then:
+ # 1) SOFT_DISABLED_BIT was cleared;
+ # 2) trace_buffered_event_disable() was called first time;
+ echo 1 > events/initcall/initcall_finish/enable
+
+ # 3. Try to call into cmdline_proc_show(), then SOFT_DISABLED_BIT was
+ # set again!!!
+ cat /proc/cmdline
+
+ # 4. Unregister the 'disable_event' command, then:
+ # 1) SOFT_DISABLED_BIT was cleared again;
+ # 2) trace_buffered_event_disable() was called second time!!!
+ echo '!cmdline_proc_show:disable_event:initcall:initcall_finish' > \
+ set_ftrace_filter
+ ```
+
+To fix it, IIUC, we can change to call trace_buffered_event_enable() at
+fist time soft-mode enabled, and call trace_buffered_event_disable() at
+last time soft-mode disabled.
