This makes life a bit easier for the drivers that include
pd.h. All pd_header_*_le() inline functions defined in pd.h
call le16_to_cpu(), and all *_LE() macros in pd.h call
cpu_to_le16().

The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

In the code path
__usb_hcd_giveback_urb()
-> wdm_in_callback()
-> service_outstanding_interrupt()
The function service_outstanding_interrupt() will unconditionally enable
interrupts during unlock and invoke usb_submit_urb() with GFP_KERNEL.
If the HCD completes in BH (like ehci does) then the context remains
atomic due local_bh_disable() and enabling interrupts does not change
this.
Defer the error case handling to a workqueue as suggested by Oliver
Neukum. In case of an error the worker performs the read out and wakes
the user.

The intr_idx_lock lock is acquired only in the completion callback of
the ->int_in_urb (iowarrior_callback()). There is only one URB that is
scheduled / completed so there can't be more than one user of the lock.
The comment says that it protects ->intr_idx and the callback is the
only place in driver that writes to it.

wa_urb_dequeue() locks multiple spinlocks while disabling interrupts:
spin_lock_irqsave(&lock1, flags);
spin_lock_irqsave(&lock2, flags2);
Obviously there is no need for the second irqsave and "flags2" variable
since interrupts are disabled at that point. Remove the second irqsave:
spin_lock_irqsave(&lock1, flags);
spin_lock(&lock2);
and eliminate the flags2 variable.

If a power failure happens while the qgroup rescan kthread is running,
the next mount operation will always fail. This is because of a recent
regression that makes qgroup_rescan_init() incorrectly return -EINVAL
when we are mounting the filesystem (through btrfs_read_qgroup_config()).
This causes the -EINVAL error to be returned regardless of any qgroup
flags being set instead of returning the error only when neither of
the flags BTRFS_QGROUP_STATUS_FLAG_RESCAN nor BTRFS_QGROUP_STATUS_FLAG_ON
are set.
A test case for fstests follows up soon.

The vm_fault_t conversion commit introduced a ret2 variable for tracking
the integer return values from internal btrfs functions. It was
sometimes returning VM_FAULT_LOCKED for pages that were actually invalid
and had been removed from the radix. Something like this:
ret2 = btrfs_delalloc_reserve_space() // returns zero on success
lock_page(page)
if (page->mapping != inode->i_mapping)
goto out_unlock;
...
out_unlock:
if (!ret2) {
...
return VM_FAULT_LOCKED;
}
This ends up triggering this WARNING in btrfs_destroy_inode()
WARN_ON(BTRFS_I(inode)->block_rsv.size);
xfstests generic/095 was able to reliably reproduce the errors.
Since out_unlock: is only used for errors, this fix moves it below the
if (!ret2) check we use to return VM_FAULT_LOCKED for success.

Commit ff3d27a048d9 ("btrfs: qgroup: Finish rescan when hit the last leaf
of extent tree") added a new exit for rescan finish.
However after finishing quota rescan, we set
fs_info->qgroup_rescan_progress to (u64)-1 before we exit through the
original exit path.
While we missed that assignment of (u64)-1 in the new exit path.
The end result is, the quota status item doesn't have the same value.
(-1 vs the last bytenr + 1)
Although it doesn't affect quota accounting, it's still better to keep
the original behavior.

kmemleak reported some memory leak on reading proc files. After adding
some debug lines, find that proc_seq_fops is using seq_release as
release handler, which won't handle the free of 'private' field of
seq_file, while in fact the open handler proc_seq_open could create
the private data with __seq_open_private when state_size is greater
than zero. So after reading files created with proc_create_seq_private,
such as /proc/timer_list and /proc/vmallocinfo, the private mem of a
seq_file is not freed. Fix it by adding the paired proc_seq_release
as the default release handler of proc_seq_ops instead of seq_release.
