This type of lock dependency is always going to exist whenever a write to
a sysfs file causes the kernel to remove its dirent. In this case,
writing to /sys/devices/block/xxx/queue/scheduler takes sd->dep_map and
sd->parent->dep_map via sysfs_get_active_two() to pin both via
sysfs_write_file(). The call to kobject_del() removes its directory
from the hierarchy which takes sd->dep_map in sysfs_deactivate() because
of 846f99749a. Eric, do we need to preempt the rwsem from being acquired
here when the dirent is already pinned because of a store to one of its
files?

This regression is fixedi (or better worked around) in your git by the
commit "leds: ALIX2: Add dependency to !GPIO_CS5335" (38b52483) but it
seems this isn't merged yet. Any plans to get this in for -rc8?
Thanks,
Daniel

This regression does still need to be listed for 2.6.33-rc8-git.
Americo is right that the warning goes away if I apply those patches from Eric,
but they look like more than we'd be adding into 2.6.33 at this stage ...
and bootup of latest git plus those patches gave me 71 messages of the form
BUG: key fxxxxxxx not in .data!

Which probably means one or two more spots that need annotation.
2.6.33 is out so these are targeted for 2.6.34...

Yes, it is still a regression 2.6.33.1 (though fixed in 2.6.34-rc1:
my guess is that it will be left as a regression in 2.6.33-stable,
since it only happens when you have chosen CONFIG_PROVE_LOCKING=y).

The policy is that we close the regression bugs after they've been fixed in the
Linus' tree, so I'm going to close it now.
If you want it to go into -stable, please let Greg know directly.
