When max_bytes is not 8 bytes aligned and bo size is larger than
max_bytes, the last 8 bytes in a ttm node may be left unchanged.
For example, on pre SDMA 4.0, max_bytes = 0x1fffff, and the bo size
is 0x200000, the problem will happen.
In order to fix the problem, we separately store the max nums of
PTEs/PDEs a single operation can set in amdgpu_vm_pte_funcs
structure, rather than inferring it from bytes limit of SDMA
constant fill, i.e. fill_max_bytes.
Together with the fix, we replace the hard code value "10" in
amdgpu_vm_bo_update_mapping() with the corresponding values from
structure amdgpu_vm_pte_funcs.

SRIOV doesn't implement PMC capability of PCIe, so it can't update
power state by reading PMC register.
Currently, amdgpu driver doesn't disable pci device when removing
driver, the enable_cnt of pci device will not be decrease to 0.
When reloading driver, pci_enable_device will do nothing as
enable_cnt is not zero. And power state will not be updated as PMC
is not support.
So current_state of pci device is not D0 state and pci_enable_msi
return fail.
Add pci_disable_device when remmoving driver to fix the issue.

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.

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.

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.

This makes the reservation per-AG, not per-filesystem. Therefore, it

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.

.__do_irq+0x88/0x200
.call_do_irq+0x14/0x24

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.

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.

If we try to delete the same tunnel twice, the first delete operation
does a lookup (l2tp_tunnel_get), finds the tunnel, calls
l2tp_tunnel_delete, which queues it for deletion by
l2tp_tunnel_del_work.
The second delete operation also finds the tunnel and calls
l2tp_tunnel_delete. If the workqueue has already fired and started
running l2tp_tunnel_del_work, then l2tp_tunnel_delete will queue the
same tunnel a second time, and try to free the socket again.
Add a dead flag to prevent firing the workqueue twice. Then we can
remove the check of queue_work's result that was meant to prevent that
race but doesn't.
Reproducer:
ip l2tp add tunnel tunnel_id 3000 peer_tunnel_id 4000 local 192.168.0.2 remote 192.168.0.1 encap udp udp_sport 5000 udp_dport 6000
