[PATCHv2 0/3] block: protect debugfs attributes using elavtor_lock

[Nilay Shroff <nilay@linux.ibm.com>]

Hi,

This patchset contains total three patches.
The first patch helps protect debugfs attributes using q->elevator_lock
instead of q->sysfs_lock.
The second patch in the series removes the goto labels from the read
methods of debugfs attributes that improves code readability and reducing
complexity.
The third patch in the series protects debugfs attribute method hctx_
busy_show using q->elevator_lock.

Please note that this patchset was unit tested against blktests and quick
xfstests with lockdep enabled.
