[GIT PULL] Block fixes for 4.14-rc2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Linus,

A round of fixes for this series. This pull request contains:

- Two sets of NVMe pull requests from Christoph:

	- Fixes for the Fibre Channel host/target to fix spec
	  compliance
	- Allow a zero keep alive timeout
	- Make the debug printk for broken SGLs work better
	- Fix queue zeroing during initialization
	- Set of RDMA and FC fixes
	- Target div-by-zero fix

- bsg double-free fix.

- Series fixing a production softlockup for repeated flusher thread
  wakeups. This is larger than it looks, each patch is trivial.

- ndb unknown ioctl fix from Josef.

- Buffered vs O_DIRECT page cache inconsistency fix. Has been floating
  around for a long time, well reviewed. From Lukas.

- brd overflow fix from Mikulas.

- Fix for a loop regression in this merge window, where using a union
  for two members of the loop_cmd turned out to be a really bad idea.
  From Omar.

- Fix for an iostat regression fix in this series, using the wrong API
  to get at the block queue. From Shaohua.

- Fix for a potential blktrace delection deadlock. From Waiman.

Please pull!
