Subject: [V5 PATCH 0/3] lightnvm: pblk: take write semaphore on metadata

# Changes since V4:
 - Rebase on top of Matias' core
 - Reorder patches to avoid in-patchset changes

# Changes since V3:
 - Encapsulate rqd dma allocations to reduce code replication (by Matias)

# Changes since V2:
 - Split the original patch between the metadata refactoring and the
   semaphore logic. This simplifies the write path, where the semaphore
   is taken.

# Changes singe V1:
    - Fix double I/O on the read path (by Matias)
    - Improve commit message (by Jens)

This patchset refactors the metadata separate write and read paths,
which simplifies how the semaphore is taken for writes.

Thanks,
Javier
