Problem: Change the counter name DLFT_CCERROR to DLFT_CCFINISH on IBM z15. This counter counts completed DEFLATE instructions with exit code 0, 1 or 2. Since exit code 0 means success and exit code 1 or 2 indicate errors, change the counter name to avoid confusion. This counter is incremented each time the DEFLATE instruction completed regardless if an error was detected or not. Solution: Rename s390 z15 counter named DFLT_CCERROR to DFLT_CCFINISH Reproduction: Command # ls /sys/devices/cpum_cf/events/DFLT_CCERROR currently succeeds. After this patch has been applied the command does not work anymore. The file does not exist anymore. Use command # ls /sys/devices/cpum_cf/events/DFLT_CCFINISH instead. Upstream-ID: 5ce1a24dd98c00a57a8fa13660648abf7e08e3ef Component: kernel 5.8 Will be integrated into 20.10 by kernel 5.8 integration. Backport available for 20.04. To be checked for 18.04 and 16.04, update will be provided Here is the backported patch.
