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.

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.

The check carried out by acpi_any_gpe_status_set() is not precise enough for the suspend-to-idle implementation in Linux and in some cases it is necessary make it skip one GPE (specifically, the EC GPE) from the check to prevent a race condition leading to a premature system resume from occurring.

Not only did this wheel did not need reinventing, but there is also an issue with it: It doesn't remove the VLAN header in a way that preserves the L2 payload checksum when that is being provided by the DSA master hw. It should recalculate checksum both for the push, before removing the header, and for the pull afterwards. But the current implementation is quite dizzying, with pulls followed immediately afterwards by pushes, the memmove is done before the push, etc. This makes a DSA master with RX checksumming offload to print stack traces with the infamous 'hw csum failure' message. So remove the dsa_8021q_remove_header function and replace it with something that actually works with inet checksumming.

2020-03-24block: move the various x86 Unix label formats out of genhd.hChristoph Hellwig
All these are just used in block/partitions/msdos.c, so move them out of the genhd.h driver included by every driver. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-24partitions/msdos: remove LINUX_SWAP_PARTITIONChristoph Hellwig
Just always use NEW_SOLARIS_X86_PARTITION and explain the situation, as that is less confusing than two names for a single value. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-24block: move the *_PARTITION enum out of genhd.hChristoph Hellwig
The enum containing the *_PARTITION symbolic names is only relevant for the partition parser. More specifically most values are MSDOS partition table system indicators and thus should go straight into msdos.c. One value is only used by the sun partition parser, and the sun and sgi partition parsers use the same value as the x86 Linux RAID indicator to also indicate RAID autodetection. Duplicate them in sun.c and sgi.c given that the different partition types use entirely different values otherwise.

2020-03-24block: move struct partition out of genhd.hChristoph Hellwig
struct partition is the on-disk format of a MSDOS partition table entry. Move it out of genhd.h into a new msdos_partition.h header and give it a msdos_ prefix to avoid confusion. Also move the magic number from block/partitions/msdos.h to the new header so that it can be used by the SCSI drivers looking at the DOS partition tables.

2020-03-24block: cleanup how md_autodetect_dev is calledChristoph Hellwig
Add a new include/linux/raid/detect.h header to declare the md_autodetect_dev prototype which can be shared between md and the partition code. Then use IS_BUILTIN to call it instead of the ifdef magic. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-24block: unexport read_dev_sector and put_dev_sectorChristoph Hellwig
read_dev_sector and put_dev_sector are now only used by the partition parsing code. Remove the export for read_dev_sector and merge it into the only caller. Clean the mess up a bit by using goto labels and the SECTOR_SHIFT constant. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-24scsi: simplify scsi_partsizeChristoph Hellwig
Call scsi_bios_ptable from scsi_partsize instead of requiring boilerplate code in the callers. Also switch the calling convention to match that of the ->bios_param instances calling this function, and use true/false for the return value instead of the weird -1 convention.

2020-03-24block: remove alloc_part_info and free_part_infoChristoph Hellwig
There isn't any good reason not to simply open code the allocation and freeing of the partition_meta_info structure. Especially as one of the branches in alloc_part_info is entirely dead code. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-24block: move sysfs methods shared by disks and partitions to genhd.cChristoph Hellwig
Move the sysfs _show methods that are used both on the full disk and partition nodes to genhd.c instead of hiding them in the partitioning code. Also move the declaration for these methods to block/blk.h so that we don't expose them to drivers. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-24block: remove __bdevnameChristoph Hellwig
There is no good reason for __bdevname to exist. Just open code printing the string in the callers. For three of them the format string can be trivially merged into existing printk statements, and in init/do_mounts.c we can at least do the scnprintf once at the start of the function, and unconditional of CONFIG_BLOCK to make the output for tiny configfs a little more helpful.

2020-03-24drivers: provide devm_platform_get_and_ioremap_resource()Dejin Zheng
Since commit "drivers: provide devm_platform_ioremap_resource()", it was wrap platform_get_resource() and devm_ioremap_resource() as single helper devm_platform_ioremap_resource(). but now, many drivers still used platform_get_resource() and devm_ioremap_resource() together in the kernel tree. The reason can not be replaced is they still need use the resource variables obtained by platform_get_resource(). so provide this helper.

2020-03-23netlink: check for null extack in cookie helpersMichal Kubecek
Unlike NL_SET_ERR_* macros, nl_set_extack_cookie_u64() and nl_set_extack_cookie_u32() helpers do not check extack argument for null and neither do their callers, as syzbot recently discovered for ethnl_parse_header(). Instead of fixing the callers and leaving the trap in place, add check of null extack to both helpers to make them consistent with NL_SET_ERR_* macros. v2: drop incorrect second Fixes tag Fixes: 2363d73a2f3e ("ethtool: reject unrecognized request flags") Reported-by: syzbot+258a9089477493cea67b@syzkaller.appspotmail.com Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.
