2020-09-07btrfs: free data reloc tree on failed mountJosef Bacik
While testing a weird problem with -o degraded, I noticed I was getting leaked root errors BTRFS warning (device loop0): writable mount is not allowed due to too many missing devices BTRFS error (device loop0): open_ctree failed BTRFS error (device loop0): leaked root -9-0 refcount 1 This is the DATA_RELOC root, which gets read before the other fs roots, but is included in the fs roots radix tree. Handle this by adding a btrfs_drop_and_free_fs_root() on the data reloc root if it exists. This is ok to do here if we fail further up because we will only drop the ref if we delete the root from the radix tree, and all other cleanup won't be duplicated.

Commit 64ecdb647ddb ("Btrfs: add one more sanity check for shared ref type") introduced extra checks for backref type. One of the requirement is, parent bytenr must be aligned to node size, which is not correct. One example is like this: 0 1G 1G+4K 2G 2G+4K | |///////////////////|//| <- A chunk starts at 1G+4K | | <- A tree block get reserved at bytenr 1G+4K Then we have a valid tree block at bytenr 1G+4K, but not aligned to nodesize (16K). Such chunk is not ideal, but current kernel can handle it pretty well. We may warn about such tree block in the future, but should not reject them. [FIX] Change the alignment requirement from node size alignment to sector size alignment. Also, to make our lives a little easier, also output @iref when btrfs_get_extent_inline_ref_type() failed, so we can locate the item easier.

2020-09-07openrisc: Fix cache API compile issue when not inliningStafford Horne

2020-09-07spi: stm32: Rate-limit the 'Communication suspended' messageMarek Vasut
The 'spi_stm32 44004000.spi: Communication suspended' message means that when using PIO, the kernel did not read the FIFO fast enough and so the SPI controller paused the transfer. Currently, this is printed on every single such event, so if the kernel is busy and the controller is pausing the transfers often, the kernel will be all the more busy scrolling this message into the log buffer every few milliseconds. That is not helpful. Instead, rate-limit the message and print it every once in a while. It is not possible to use the default dev_warn_ratelimited(), because that is still too verbose, as it prints 10 lines (DEFAULT_RATELIMIT_BURST) every 5 seconds (DEFAULT_RATELIMIT_INTERVAL). The policy here is to print 1 line every 50 seconds (DEFAULT_RATELIMIT_INTERVAL * 10), because 1 line is more than enough and the cycles saved on printing are better left to the CPU to handle the SPI. However, dev_warn_once() is also not useful, as the user should be aware that this condition is possibly recurring or ongoing. Thus the custom rate-limit policy. Finally, turn the message from dev_warn() to dev_dbg(), since the system does not suffer any sort of malfunction if this message appears, it is just slowing down. This further reduces the printing into the log buffer and frees the CPU to do useful work.

Be consistent with other virtual block devices (loop, nbd, dm, md, etc) and require CAP_SYS_ADMIN in the initial user namespace for mapping and unmapping, and also for dumping the configuration string and refreshing the image header.

Setting F2 block size to 128 bytes for BCM4329 allows to significantly improve RX throughput on NVIDIA Tegra20. Before this change the throughput was capped to 30 Mbit/s on Tegra, now throughput is at 40 Mbit/s, which is a maximum throughput for the BCM4329 chip. The F2 block size is borrowed from the downstream BCMDHD driver. The comment in the BCMDHD driver says that 128B improves throughput and turns out that it works for the brcmfmac as well.

2020-09-07mmc: sdio: Use mmc_pre_req() / mmc_post_req()Adrian Hunter
SDHCI changed from using a tasklet to finish requests, to using an IRQ thread i.e. commit c07a48c2651965 ("mmc: sdhci: Remove finish_tasklet"). Because this increased the latency to complete requests, a preparatory change was made to complete the request from the IRQ handler if possible i.e. commit 19d2f695f4e827 ("mmc: sdhci: Call mmc_request_done() from IRQ handler if possible"). That alleviated the situation for MMC block devices because the MMC block driver makes use of mmc_pre_req() and mmc_post_req() so that successful requests are completed in the IRQ handler and any DMA unmapping is handled separately in mmc_post_req(). However SDIO was still affected, and an example has been reported with up to 20% degradation in performance. Looking at SDIO I/O helper functions, sdio_io_rw_ext_helper() appeared to be a possible candidate for making use of asynchronous requests within its I/O loops, but analysis revealed that these loops almost never iterate more than once, so the complexity of the change would not be warrented. Instead, mmc_pre_req() and mmc_post_req() are added before and after I/O submission (mmc_wait_for_req) in mmc_io_rw_extended(). This still has the potential benefit of reducing the duration of interrupt handlers, as well as addressing the latency issue for SDHCI. It also seems a more reasonable solution than forcing drivers to do everything in the IRQ handler.

2020-09-07mmc: mmc_spi: Allow the driver to be built when CONFIG_HAS_DMA is unsetUlf Hansson
The commit cd57d07b1e4e ("sh: don't allow non-coherent DMA for NOMMU") made CONFIG_NO_DMA to be set for some platforms, for good reasons. Consequentially, CONFIG_HAS_DMA doesn't get set, which makes the DMA mapping interface to be built as stub functions, but also prevent the mmc_spi driver from being built as it depends on CONFIG_HAS_DMA. It turns out that for some odd cases, the driver still relied on the DMA mapping interface, even if the DMA was not actively being used. To fixup the behaviour, let's drop the build dependency for CONFIG_HAS_DMA. Moreover, as to allow the driver to succeed probing, let's move the DMA initializations behind "#ifdef CONFIG_HAS_DMA".

2020-09-07mmc: sdhci-msm: Add retries when all tuning phases are found validDouglas Anderson
As the comments in this patch say, if we tune and find all phases are valid it's _almost_ as bad as no phases being found valid. Probably all phases are not really reliable but we didn't detect where the unreliable place is. That means we'll essentially be guessing and hoping we get a good phase. This is not just a problem in theory. It was causing real problems on a real board. On that board, most often phase 10 is found as the only invalid phase, though sometimes 10 and 11 are invalid and sometimes just 11. Some percentage of the time, however, all phases are found to be valid. When this happens, the current logic will decide to use phase 11. Since phase 11 is sometimes found to be invalid, this is a bad choice. Sure enough, when phase 11 is picked we often get mmc errors later in boot. I have seen cases where all phases were found to be valid 3 times in a row, so increase the retry count to 10 just to be extra sure.

The commit 61d7437ed1390 ("mmc: sdhci-acpi: Fix HS400 tuning for AMDI0040") broke resume for eMMC HS400. When the system suspends the eMMC controller is powered down. So, on resume we need to reinitialize the controller. Although, amd_sdhci_host was not getting cleared, so the DLL was never re-enabled on resume. This results in HS400 being non-functional. To fix the problem, this change clears the tuned_clock flag, clears the dll_enabled flag and disables the DLL on reset.

2020-09-06enic: switch from 'pci_' to 'dma_' APIChristophe JAILLET
The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'vnic_dev_classifier()', 'vnic_dev_fw_info()', 'vnic_dev_notify_set()' and 'vnic_dev_stats_dump()' (vnic_dev.c) GFP_ATOMIC must be used because its callers take a spinlock before calling these functions. When memory is allocated in '__enic_set_rsskey()' and 'enic_set_rsscpu()' GFP_ATOMIC must be used because they can be called with a spinlock. The call chain is: enic_reset <-- takes 'enic->enic_api_lock' --> enic_set_rss_nic_cfg --> enic_set_rsskey --> __enic_set_rsskey <-- uses dma_alloc_coherent --> enic_set_rsscpu <-- uses dma_alloc_coherent When memory is allocated in 'vnic_dev_init_prov2()' GFP_ATOMIC must be used because a spinlock is hidden in the ENIC_DEVCMD_PROXY_BY_INDEX macro, when this function is called in 'enic_set_port_profile()'. When memory is allocated in 'vnic_dev_alloc_desc_ring()' GFP_KERNEL can be used because it is only called from 5 functions ('vnic_dev_init_devcmd2()', 'vnic_cq_alloc()', 'vnic_rq_alloc()', 'vnic_wq_alloc()' and 'enic_wq_devcmd2_alloc()'. 'vnic_dev_init_devcmd2()': already uses GFP_KERNEL and no lock is taken in the between. 'enic_wq_devcmd2_alloc()': is called from ' vnic_dev_init_devcmd2()' which already uses GFP_KERNEL and no lock is taken in the between. 'vnic_cq_alloc()', 'vnic_rq_alloc()', 'vnic_wq_alloc()': are called from 'enic_alloc_vnic_resources()' 'enic_alloc_vnic_resources()' has only 2 call chains: 1) enic_probe --> enic_dev_init --> enic_alloc_vnic_resources 'enic_probe()' is a probe function and no lock is taken in the between 2) enic_set_ringparam --> enic_alloc_vnic_resources 'enic_set_ringparam()' is a .set_ringparam function (see struct ethtool_ops). It seems to only take a mutex and no spinlock.

2020-09-06net: dsa: rtl8366: Properly clear member configLinus Walleij
When removing a port from a VLAN we are just erasing the member config for the VLAN, which is wrong: other ports can be using it. Just mask off the port and only zero out the rest of the member config once ports using of the VLAN are removed from it.

It's nice if the phy is online before we register the netdev so try to do that first. Stop trying to do "second tried" to register the phy, it works perfectly fine the first time. Stop remvoving the phy in uninit. Remove it when the driver is remove():d, symmetric to where it is added, in probe().
