Subject: [PATCH 0/5] lightnvm: pblk: audit mempool usage

As suggested by Jens [1], I audited all mempools on pblk.

This patche series (i) fixes bad mempool allocations that did not
guarantee forward progress and downsizes the sizes of some overused
mempools, (ii) removes unnecessary checks, and (iii) eliminates some
mempools that where introduced in early versions of pblk.

Javier González (5):
  lightnvm: pblk: fix min size for page mempool
  lightnvm: pblk: simplify work_queue mempool
  lightnvm: pblk: decouple read/erase mempools
  lightnvm: pblk: do not use a mempool for line bitmaps
  lightnvm: pblk: remove checks on mempool alloc.
