Subject: [PATCH 0/4] block: fix partition use-after-free and optimization
Date: Thu,  9 Jan 2020 14:21:05 +0800	[thread overview]
Message-ID: <20200109062109.2313-1-ming.lei@redhat.com> (raw)

Hi,

The 1st patch fixes one use-after-free on cached last_lookup partition.

The other 3 patches optimizes partition uses in IO path.



Ming Lei (4):
  block: fix use-after-free on cached last_lookup partition
  block: only define 'nr_sects_seq' in hd_part for 32bit SMP
  block: re-organize fields of 'struct hd_part'
  block: don't hold part0's refcount in IO path
