2020-03-25block/diskstats: replace time_in_queue with sum of request timesKonstantin Khlebnikov
Column "time_in_queue" in diskstats is supposed to show total waiting time of all requests. I.e. value should be equal to the sum of times from other columns. But this is not true, because column "time_in_queue" is counted separately in jiffies rather than in nanoseconds as other times. This patch removes redundant counter for "time_in_queue" and shows total time of read, write, discard and flush requests.

2020-03-25block/diskstats: accumulate all per-cpu counters in one passKonstantin Khlebnikov
Reading /proc/diskstats iterates over all cpus for summing each field. It's faster to sum all fields in one pass. Hammering /proc/diskstats with fio shows 2x performance improvement: fio --name=test --numjobs=$JOBS --filename=/proc/diskstats \ --size=1k --bs=1k --fallocate=none --create_on_open=1 \ --time_based=1 --runtime=10 --invalidate=0 --group_report JOBS=1 JOBS=10 Before: 7k iops 64k iops After: 18k iops 120k iops Also this way code is more compact: add/remove: 1/0 grow/shrink: 0/2 up/down: 194/-1540 (-1346) Function old new delta part_stat_read_all - 194 +194 diskstats_show 1344 631 -713 part_stat_show 1219 392 -827 Total: Before=14966947, After=14965601, chg -0.01% Signed-off-by: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-25block/diskstats: more accurate approximation of io_ticks for slow disksKonstantin Khlebnikov
Currently io_ticks is approximated by adding one at each start and end of requests if jiffies counter has changed. This works perfectly for requests shorter than a jiffy or if one of requests starts/ends at each jiffy. If disk executes just one request at a time and they are longer than two jiffies then only first and last jiffies will be accounted. Fix is simple: at the end of request add up into io_ticks jiffies passed since last update rather than just one jiffy. Example: common HDD executes random read 4k requests around 12ms. fio --name=test --filename=/dev/sdb --rw=randread --direct=1 --runtime=30 & iostat -x 10 sdb Note changes of iostat's "%util" 8,43% -> 99,99% before/after patch: Before: Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sdb 0,00 0,00 82,60 0,00 330,40 0,00 8,00 0,96 12,09 12,09 0,00 1,02 8,43 After: Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sdb 0,00 0,00 82,50 0,00 330,00 0,00 8,00 1,00 12,10 12,10 0,00 12,12 99,99 Now io_ticks does not loose time between start and end of requests, but for queue-depth > 1 some I/O time between adjacent starts might be lost. For load estimation "%util" is not as useful as average queue length, but it clearly shows how often disk queue is completely empty.

2020-03-25ARM: dts: exynos: Fix regulator node aliasing on Midas-based boardsMarek Szyprowski
Commit d4ec0cb05064 ("ARM: dts: exynos: Add support for the touch-sensitive buttons on Midas family") added a new fixed regulator ("voltage-regulator-6") to base "midas" .dtsi, but it didn't update the clients of that .dtsi, which define their own fixed regulators starting from the "voltage-regulator-6". This results in aliasing of the regulator dt nodes and breaks operation of OLED panel due to lack of power supply. Fix this by increasing the numbers in the fixed regulator names for those boards.

2020-03-24scsi: sd: Fix optimal I/O size for devices that change reported valuesMartin K. Petersen
Some USB bridge devices will return a default set of characteristics during initialization. And then, once an attached drive has spun up, substitute the actual parameters reported by the drive. According to the SCSI spec, the device should return a UNIT ATTENTION in case any reported parameters change. But in this case the change is made silently after a small window where default values are reported. Commit a83da8a4509d ("scsi: sd: Optimal I/O size should be a multiple of physical block size") validated the reported optimal I/O size against the physical block size to overcome problems with devices reporting nonsensical transfer sizes. However, this validation did not account for the fact that aforementioned devices will return default values during a brief window during spin-up. The subsequent change in reported characteristics would invalidate the checking that had previously been performed. Unset a previously configured optimal I/O size should the sanity checking fail on subsequent revalidate attempts.

2020-03-25zonfs: Fix handling of read-only zonesDamien Le Moal
The write pointer of zones in the read-only consition is defined as invalid by the SCSI ZBC and ATA ZAC specifications. It is thus not possible to determine the correct size of a read-only zone file on mount. Fix this by handling read-only zones in the same manner as offline zones by disabling all accesses to the zone (read and write) and initializing the inode size of the read-only zone to 0). For zones found to be in the read-only condition at runtime, only disable write access to the zone and keep the size of the zone file to its last updated value to allow the user to recover previously written data. Also fix zonefs documentation file to reflect this change. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com>

This test covers two recent fixes: 07f8e4d0fddb ("tcp: also NULL skb->dev when copy was needed") and b738a185beaa ("tcp: ensure skb->dev is NULL before leaving TCP stack"). 2) The fwd action breaks with ifb. For safety in next extensions, make sure the fwd action only runs from ingress until it is extended to be used from a different hook. 3) The pipapo set type now reports EEXIST in case of subrange overlaps. Update the rbtree set to validate range overlaps, so far this validation is only done only from userspace. From Stefano Brivio. ==================== Signed-off-by: David S.
