[RFC PATCH 0/2] nfsd: clean up CB_LAYOUTRECALL handling

[Jeff Layton <jlayton@poochiereds.net>]

This is a proposal that should follow the broad outlines of what HCH
was suggesting for CB_LAYOUTRECALL. It changes the code to treat 0
and NFS4ERR_DELAY returns equivalently, and also implements a scheme
to give up on the client after two lease periods.

Note that this is _not_ tested, since I don't have a pnfs test rig on
which to test this.

Jeff Layton (2):
  nfsd: don't hold ls_mutex across a layout recall
  nfsd: give up on CB_LAYOUTRECALLs after two lease periods
