# 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
