Hi Al,
I think there is a race condition between iget_locked() and evict_inodes().
evict_inodes() checks i_count and if zero proceeds to take i_lock then set
I_FREEING and eventually disposes of the inode.
But a concurrent iget_locked() takes i_lock and then increments i_count.
Thus if the eve

Being able to write to spmi registers via userspace is required
for quick debug and development. Enable it.
The regmap framework uses dev_name to create debugfs dir names.
So update the spmi devices to have proper names.

It's not an error if the IBM ACPI pseudo-device isn't present, it merely
means the kernel isn't running on that IBM hardware. Get rid of the
