Hello,
This patchset kills one big kind of lockdep warning by cutting
dependency between q->debugfs_lock and mm->mmap_lock around copy_to_user()
and copy_from_user(().
Ming Lei (2):
blktrace: don't centralize grabbing q->debugfs_mutex in
blk_trace_ioctl
blktrace: move copy_[to|from]_user() out of ->debugfs_lock
