Subject: [PATCH 0/2] Don't do pNFS I/O when not holding a layout
Date: Wed,  5 Aug 2020 16:24:29 -0400	[thread overview]
Message-ID: <20200805202431.627013-1-trondmy@kernel.org> (raw)

From: Trond Myklebust <trond.myklebust@hammerspace.com>

We recently discovered a couple of issues in the pNFS client that can
cause it to return a layout while some of the layout segments being
returned are still in use for I/O.

The following 2 patches will add appropriate tests to ensure this
cannot happen, and that the layoutreturn call is delayed until
the outstanding I/O is finished.

Trond Myklebust (2):
  NFS: Don't move layouts to plh_return_segs list while in use
  NFS: Don't return layout segments that are in use
