George Boole would have noticed a slight error in 4.16 commit 69d763fc ("mm: pin address_space before dereferencing it while isolating an LRU page"). Fix it, to match both the comment above it, and the original behaviour. Although anonymous pages are not marked PageDirty at first, we have an old habit of calling SetPageDirty when a page is removed from swap cache: so there's a category of ex-swap pages that are easily migratable, but were inadvertently excluded from compaction's async migration in 4.16.

Swapping load on huge=always tmpfs (with khugepaged tuned up to be very eager, but I'm not sure that is relevant) soon hung uninterruptibly, waiting for page lock in shmem_getpage_gfp()'s find_lock_entry(), most often when "cp -a" was trying to write to a smallish file. Debug showed that the page in question was not locked, and page->mapping NULL by now, but page->index consistent with having been in a huge page before. Reproduced in minutes on a 4.15 kernel, even with 4.17's 605ca5ed ("mm/huge_memory.c: reorder operations in __split_huge_page_tail()") added in; but took hours to reproduce on a 4.17 kernel (no idea why). The culprit proved to be the __ClearPageDirty() on tails beyond i_size in __split_huge_page(): the non-atomic __bitoperation may have been safe when 4.8's baa355fd ("thp: file pages support for split_huge_page()") introduced it, but liable to erase PageWaiters after 4.10's 62906027 ("mm: add PageWaiters indicating tasks are waiting for a page bit").

由 Darrick J. Wong 提交于
In inode_init_always(), we clear the inode mapping flags, which clears any retained error (AS_EIO, AS_ENOSPC) bits. Unfortunately, we do not also clear wb_err, which means that old mapping errors can leak through to new inodes. This is crucial for the XFS inode allocation path because we recycle old in-core inodes and we do not want error state from an old file to leak into the new file. This bug was discovered by running generic/036 and generic/047 in a loop and noticing that the EIOs generated by the collision of direct and buffered writes in generic/036 would survive the remount between 036 and 047, and get reported to the fsyncs (on different files!) in generic/047.

When a GID entry is invalid EAGAIN is returned. This is an incorrect error code, there is nothing that will make this GID entry valid again in bounded time. Some user space tools fail incorrectly if EAGAIN is returned here, and this represents a small ABI change from earlier kernels. The first patch in the Fixes list makes entries that were valid before to become invalid, allowing this code to trigger, while the second patch in the Fixes list introduced the wrong EAGAIN. Therefore revert the return result to EINVAL which matches the historical expectations of the ibv_query_gid_type() API of the libibverbs user space library.

I used bad names in my clumsiness when rewriting many board files to use GPIO descriptors instead of platform data. A few had the platform_device ID set to -1 which would indeed give the device name "i2c-gpio". But several had it set to >=0 which gives the names "i2c-gpio.0", "i2c-gpio.1" ... Fix the offending instances in the ARM tree. Sorry for the mess.

This patch is a partial revert of commit abd7d097 ("arm64: dts: hikey: Enable HS200 mode on eMMC") which has been causing eMMC corruption on my HiKey board.

This patch fixes the Inside Secure driver which uses a memtset() call to set an MMIO area from the cryptographic engine to 0. This is wrong as memset() isn't guaranteed to work on MMIO for many reasons. This led to kernel paging request panics in certain cases. Use memset_io() instead.
