H A D | procfs-diskstats | bdca3c87 Wed Jul 18 06:47:40 CDT 2018 Michael Callahan <michaelcallahan@fb.com> block: Track DISCARD statistics and output them in stat and diskstat
Add tracking of REQ_OP_DISCARD ios to the partition statistics and append them to the various stat files in /sys as well as /proc/diskstats. These are tracked with the same four stats as reads and writes:
Number of discard ios completed. Number of discard ios merged Number of discard sectors completed Milliseconds spent on discard requests
This is done via adding a new STAT_DISCARD define to genhd.h and then using it to index that stat field for discard requests.
tj: Refreshed on top of v4.17 and other previous updates.
