Hi Jens,
below is the first batch of nvme updates for 5.2. This includes the
performance improvements for single segment I/O on PCIe, which introduce
new block helpers, so it might be a good idea to get them in early.
- various performance optimizations in the PCIe code (Keith and me)
- new block helpers to support the above (me)
- nvmet error conversion cleanup (me)
- nvmet-fc variable sized array cleanup (Gustavo)
- passthrough ioctl error printk cleanup (Kenneth)
- small nvmet fixes (Max)
- endianess conversion cleanup (Max)
- nvmet-tcp faspath completion optimization (Sagi)
The following changes since commit 2b24e6f63ac9e817630424c6d8f008256348dfc4:
block: bio: ensure newly added bio flags don't override BVEC_POOL_IDX (2019-04-04 09:30:37 -0600)
