[PULL] nfsd changes for 3.17

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

 



Please pull nfsd changes for 3.17 from

  git://linux-nfs.org/~bfields/linux.git for-3.17

This includes a major rewrite of the NFSv4 state code, which has always
depended on a single mutex.  As an example, open creates are no longer
serialized, fixing a performance regression on NFSv3->NFSv4 upgrades.
Thanks to Jeff, Trond, and Benny, and to Christoph for review.

Also some RDMA fixes from Chuck Lever and Steve Wise, and miscellaneous
fixes from Kinglong Mee and others.
