[PATCH] drm/nouveau/dmem: missing mutex_lock in error path
In nouveau_dmem_pages_alloc(), the drm->dmem->mutex is unlocked before
calling nouveau_dmem_chunk_alloc().
Reacquire the lock before continuing to the next page.

I found this while testing Jason Gunthorpe's hmm tree but this is
independant of those changes. I guess it could go through

[PATCH] Btrfs: pass lockdep rwsem metadata to async commit transaction
The freeze rwsem is taken by sb_start_intwrite() and dropped during the
commit_ or end_transaction(). In the async case, that happens in a worker
thread. Tell lockdep the calling thread is releasing ownership of the
rwsem and the async thread is picking it up.
Josef and I worked out a more complicated solution that made the async
commit thread join and potentially get a later transaction, but
