2017-09-26drm/amdgpu: Track pending retry faults in IH and VM (v2)Felix Kuehling6-1/+180
IH tracks pending retry faults in a hash table for fast lookup in interrupt context. Each VM has a short FIFO of pending VM faults for processing in a bottom half. The IH prescreening stage adds retry faults and filters out repeated retry interrupts to minimize the impact of interrupt storms. It's the VM's responsibility remove pending faults once they are handled. For now this is only done when the VM is destroyed. v2: - Made the hash table smaller and the FIFO longer. I never want the FIFO to fill up, because that would make prescreen take longer. 128 pending page faults should be enough to keep migrations busy.

2017-09-26drm/amd: Closed hash table with low overhead (v2)Felix Kuehling6-0/+1045
This adds a statically sized closed hash table implementation with low memory and CPU overhead. The API is inspired by kfifo. Storing, retrieving and deleting data does not involve any dynamic memory management, which makes it ideal for use in interrupt context. Static memory usage per entry comprises a 32 or 64 bit hash key, two bits for occupancy tracking and the value size stored in the table. No list heads or pointers are needed. Therefore this data structure should be quite cache-friendly, too. It uses linear probing and lazy deletion. During lookups free space is reclaimed and entries relocated to speed up future lookups. v2: squash in do_div and _BITOPS_LONG_SHIFT fixes Signed-off-by: Felix Kuehling <[email protected]> Acked-by: Christian König <[email protected]> Acked-by: Alex Deucher <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2017-09-26xfs: revert "xfs: factor rmap btree size into the indlen calculations"Darrick J. Wong1-15/+2
In commit fd26a88093ba we added a worst case estimate for rmapbt blocks needed to satisfy the block mapping request. Since then, we added the ability to reserve enough space in each AG such that we should never run out of blocks to grow the rmapbt, which makes this calculation unnecessary. Revert the commit because it makes the extra delalloc indlen accounting unnecessary and incorrect.

2017-09-26xfs: update i_size after unwritten conversion in dio completionEryu Guan5-19/+28
Since commit d531d91d6990 ("xfs: always use unwritten extents for direct I/O writes"), we start allocating unwritten extents for all direct writes to allow appending aio in XFS. But for dio writes that could extend file size we update the in-core inode size first, then convert the unwritten extents to real allocations at dio completion time in xfs_dio_write_end_io(). Thus a racing direct read could see the new i_size and find the unwritten extents first and read zeros instead of actual data, if the direct writer also takes a shared iolock. Fix it by updating the in-core inode size after the unwritten extent conversion. To do this, introduce a new boolean argument to xfs_iomap_write_unwritten() to tell if we want to update in-core i_size or not.

2017-09-26iomap_dio_rw: Allocate AIO completion queue before submitting dioChandan Rajendra1-7/+7
Executing xfs/104 test in a loop on Linux-v4.13 kernel on a ppc64 machine can cause the following NULL pointer dereference, .queue_work_on+0x4c/0x80 .iomap_dio_bio_end_io+0xbc/0x1f0 .bio_endio+0x118/0x1f0 .blk_update_request+0xd0/0x470 .blk_mq_end_request+0x24/0xc0 .lo_complete_rq+0x40/0xe0 .__blk_mq_complete_request_remote+0x28/0x40 .flush_smp_call_function_queue+0xc4/0x1e0 .smp_ipi_demux_relaxed+0x8c/0x100 .icp_hv_ipi_action+0x54/0xa0 .__handle_irq_event_percpu+0x84/0x2c0 .handle_irq_event_percpu+0x28/0x80 .handle_percpu_irq+0x78/0xc0 .generic_handle_irq+0x40/0x70 .__do_irq+0x88/0x200 .call_do_irq+0x14/0x24 .do_IRQ+0x84/0x130 This occurs due to the following sequence of events, 1. Allocate dio for Direct I/O write. 2. Invoke iomap_apply() until iov_iter_count() bytes have been submitted. - Assume that we have submitted atleast one bio. Hence iomap_dio->ref value will be >= 2. - If during the second iteration, iomap_apply() ends up returning -ENOSPC, we would break out of the loop and since the 'ret' value is a negative number we end up not allocating memory for super_block->s_dio_done_wq. 3. Meanwhile, iomap_dio_bio_end_io() is invoked for bios that have been submitted and here the code ends up dereferencing the NULL pointer stored at super_block->s_dio_done_wq. This commit fixes the bug by allocating memory for super_block->s_dio_done_wq before iomap_apply() is invoked.

2017-09-26xfs: validate bdev support for DAX inode flagRoss Zwisler1-1/+2
Currently only the blocksize is checked, but we should really be calling bdev_dax_supported() which also tests to make sure we can get a struct dax_device and that the dax_direct_access() path is working. This is the same check that we do for the "-o dax" mount option in xfs_fs_fill_super(). This does not fix the race issues that caused the XFS DAX inode option to be disabled, so that option will still be disabled. If/when we re-enable it, though, I think we will want this issue to have been fixed. I also do think that we want to fix this in stable kernels.

2017-09-26btrfs: log csums for all modified extentsJosef Bacik1-2/+10
Amir reported a bug discovered by his cleaned up version of my dm-log-writes xfstests where we were missing csums at certain replay points. This is because fsx was doing an msync(), which essentially fsync()'s a specific range of a file. We will log all modified extents, but only search for the checksums in the range we are being asked to sync. We cannot simply log the extents in the range we're being asked because we are logging the inode item as it is currently, which if it has had a i_size update before the msync means we will miss extents when replaying. We could possibly get around this by marking the inode with the transaction that extended the i_size to see if we have this case, but this would be racy and we'd have to lock the whole range of the inode to make sure we didn't have an ordered extent outside of our range that was in the middle of completing. Fix this simply by keeping track of the modified extents range and logging the csums for the entire range of extents that we are logging. This makes the xfstest pass.

2017-09-26Btrfs: fix unexpected result when dio reading corrupted blocksLiu Bo1-5/+2
commit 4246a0b63bd8 ("block: add a bi_error field to struct bio") changed the logic of how dio read endio reports errors. For single stripe dio read, %bio->bi_status reflects the error before verifying checksum, and now we're updating it when data block matches with its checksum, while in the mismatching case, %bio->bi_status is not updated to relfect that. When some blocks in a file have been corrupted on disk, reading such a file ends up with 1) checksum errors are reported in kernel log 2) read(2) returns successfully with some content being 0x01. In order to fix it, we need to report its checksum mismatch error to the upper layer (dio layer in this case) as well.
