Subject[V4 PATCH 0/2] lightnvm: pblk: take write semaphore on metadata
Date
# 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
