+What is it ?
+----------
+ioblame is a IO profiler. It gives a detailed listing of the list of
+files that running pids are doing IO to (with the aggregate amount of
+read/write to each file). The goal is that using this tool, app
+developers can identify IO heavy paths, and tune them, then
+iteratively run this tool again to measure improvements/IO reduction.
+
+ioblame is implemented as a collection of kernel filesystem
+tracepoints, and a script.
+
+What does the output from ioblame look like ?
+-------------------------------------------
+ioblame gives 2 different views.
+
+File view is the default.
+
+1) File view : For each file, it gives a list of pids that are doing
+IO on that file (it also gives the amount of IO each pid does and
+the aggregate amount of IO done to the file by all pids).

+
+And ditto for writes.
+
+For the -p, writepages option, ioblame does not (and cannot) give you
+the app/pid that did the original write (since the write most likely
+happens from a flush thread or VM reclaim). In this mode, we only get
+the pathname of the file and the amount of data written out.
+
+Finally, it reports the total amount of file data IO done by pids and
+the total IO done to the block device. So we can look at IO overheads
+(eg block level prefetching, filesystem metadata overhead etc).
+
+For detailed examples, look at ioblame-gmail-launch.example and
+ioblame-gmail-run.example.
+
+How do I run ioblame ?
+--------------------
+ioblame -r	[ I am only interested in reads ]
+ioblame -w	[ I am only interested in writes ]
+ioblame -p	[ I am only interested in writepage(s) - mmap'ed writes ]
+ioblame -r -w -p [ I am only interested in reads, writes and writepages ]
+and finally, -v adds the PID view
+
+1) The most common way of running ioblame is to start ioblame, then go
+off and launch the app(s) of interest, do interesting stuff with the
+app(s), and when finished with the app, hit ^C ONCE on
+ioblame. Hitting ^C once will cause ioblame to catch the signal, break
+out of the sleep, terminate its tracing, and process the ftraces and
+dump out IO stats for the app.
+
+example :
+
+srmohan0.mtv.corp.google.com> sh ioblame.sh  -r -w -p
+Found aosp_gobo Device
+OK to kill sleep when test is done
+^Csignal INT received, killing streaming trace capture
+
+(at this point, run your apps, when done type ^C ONCE) and output will
+appear on stdout.
+
+2) Sometimes, we want to do IO profiling in a different way (instead of
+running something and then hitting ^C on ioblame). For instance, we
+might want to do IO profiling related to the launch of an App. This
+requires you to modify the script slightly, as described in the next
+paragraph.
+
+If you want to do IO profiling related to App launch, you need to modify
+2 functions - prep_to_do_something and do_something. Again examples of
+changes to these functions clarifies things better :
+
+prep_to_do_something() {
+    adb shell "am force-stop com.google.android.gm" # This line I added for example
+    	      	  	     			    # stops the running app (gmail)
+    adb shell 'echo 3 > /proc/sys/vm/drop_caches'
+    sleep 1
+}
+
+do_something() {
+    # Arrange things so that the first SIGINT will kill the
+    # child process (sleep), but will return to the parent.
+#    trap 'catch_sigint'  INT
+#    echo "OK to kill sleep when test is done"
+#    sleep 1d
+     # For the purpose of this example, I commented out the above 3 lines that
+     # make ioblame sleep forever after catching the SIGINT and instead it launches
+     # gmail, waiting for launch to complete. When launch completes, ioblame will
+     # stop tracing, and process the traces
+    adb shell "am start -W -n com.google.android.gm/.ConversationListActivityGmail"
+}
+
+Limitations :
+-----------
+The ioblame kernel tracepoints currently only cover the getpage(s)
+path (so all filesystem reads) and filesystem write() syscalls. There
+are no tracepoints in the putpage(s) paths. This is because when
+putpage(s) is called, we most often cannot tell which thread/pid has
+dirtied the page that is being written out, because the majority of
+putpage(s) happen from the flush threads or from the pageout
+threads. The upshot of this is the mmap'ed writes are not reported by
+ioblame. In practice, while mmap'ed reads are very common, mmap'ed
+writes are infrequent.
+
+Kernel Patches Required :
+-----------------------
+ioblame needs the kernel to be patched with these 3 kernel patches.
+Without these patches, ioblame won't work at all.
