The new implementation of bd_link_disk_holder() added by 49731baa (block: restore multiple bd_link_disk_holder() support) didn't get an extra reference for the holder_dir kobject of the slave bdev; however, bdev kills holder_dir on removal, not release, so if the slave bdev is removed while there are holder links, the holder_dir will be destroyed while there still are holder links, which leads to oops later when bd_unlink_disk_order() tries to remove those links. Make bd_link_disk_holder() grab an extra reference for the slave's holder_dir and put it in bd_unlink_disk_holder().

Adam Kovari and others reported that disconnecting an USB drive with an ntfs-3g filesystem would cause "kernel BUG at fs/inode.c:1421!" to be triggered. The BUG could be traced back to ioctl(BLKBSZSET), which would erroneously decrement the refcount on the bdev. This is because blkdev_get() expects the refcount to be already incremented and either returns success or decrements the refcount and returns an error. The bug was introduced by e525fd89 (block: make blkdev_get/put() handle exclusive access), which didn't take into account this behavior of blkdev_get().

Robert Swiecki reported a BUG_ON(page_mapped) from a fuzzer, punching a hole with madvise(,, MADV_REMOVE). That path is under mutex, and cannot be explained by lack of serialization in unmap_mapping_range(). Reviewing the code, I found one place where vm_truncate_count handling should have been updated, when I switched at the last minute from one way of managing the restart_addr to another: mremap move changes the virtual addresses, so it ought to adjust the restart_addr. But rather than exporting the notion of restart_addr from memory.c, or converting to restart_pgoff throughout, simply reset vm_truncate_count to 0 to force a rescan if mremap move races with preempted truncation. We have no confirmation that this fixes Robert's BUG, but it is a fix that's worth making anyway.

Michael Leun reported that running parallel opens on a fuse filesystem can trigger a "kernel BUG at mm/truncate.c:475" Gurudas Pai reported the same bug on NFS. The reason is, unmap_mapping_range() is not prepared for more than one concurrent invocation per inode. For example: thread1: going through a big range, stops in the middle of a vma and stores the restart address in vm_truncate_count. thread2: comes in with a small (e.g. single page) unmap request on the same vma, somewhere before restart_address, finds that the vma was already unmapped up to the restart address and happily returns without doing anything. Another scenario would be two big unmap requests, both having to restart the unmapping and each one setting vm_truncate_count to its own value. This could go on forever without any of them being able to finish. Truncate and hole punching already serialize with i_mutex. Other callers of unmap_mapping_range() do not, and it's difficult to get i_mutex protection for all callers. In particular ->d_revalidate(), which calls invalidate_inode_pages2_range() in fuse, may be called with or without i_mutex. This patch adds a new mutex to 'struct address_space' to prevent running multiple concurrent unmap_mapping_range() on the same mapping. [ We'll hopefully get rid of all this with the upcoming mm preemptibility series by Peter Zijlstra, the "mm: Remove i_mmap_mutex lockbreak" patch in particular.

It looks like gen2 has a peculiar interleaved 2-row inter-tile layout. Probably inherited from i81x which had 2kb tiles (which naturally fit an even-number-of-tile-rows scheme to fit onto 4kb pages). There is no other mention of this in any docs (also not in the Intel internal documention according to Chris Wilson). Problem manifests itself in corruptions in the second half of the last tile row (if the bo has an odd number of tiles). Which can only happen with relaxed tiling (introduced in a00b10c3). So reject set_tiling calls that don't satisfy this constrain to prevent broken userspace from causing havoc. While at it, also check the size for newer chipsets.

Commit 8ee294cd converted serio subsystem event handling from using a dedicated thread to using common workqueue. Unfortunately, this regressed our boot times, due to the fact that serio jobs take long time to execute. While the new concurrency managed workqueue code manages long-playing works just fine and schedules additional workers as needed, such works wreck havoc among remaining users of flush_scheduled_work(). To solve this problem let's move serio/gameport works from system_wq to system_long_wq which nobody tries to flush.

This errata occurs when the ARDY interrupt generation is enabled. At the begining of every new transaction the ARDY interrupt is cleared. On continuous i2c transactions where after clearing the ARDY bit from I2C_STAT register (clearing the interrupt), the IRQ line is reasserted and the I2C_STAT[ARDY] bit set again on 1. In fact, the ARDY status bit is not cleared at the write access to I2C_STAT[ARDY] and only the IRQ line is deasserted and then reasserted. This is not captured in the usual errata documents. The workaround is to have a double clear of ARDY status in irq handler.
