Subject: [PATCH 0/5] lightnvm: pblk: audit mempool usage
Date: Thu, 14 Sep 2017 12:33:42 +0200 [thread overview]
Message-ID: <1505385227-28706-1-git-send-email-javier@cnexlabs.com> (raw)
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.
