  "message": "pnfs: change layout state seqlock to a spinlock\n\nThis prepares for future changes, where the layout state needs\nto change atomically with several other variables.  In particular,\nit will need to know if lo-\u003esegs is empty, as we test that instead\nof manipulating the NFS_LAYOUT_STATEID_SET bit.  Moreover, the\nlayoutstateid is not really a read-mostly structure, as it is\nwritten almost as often as it is read.\n\nThe behavior of pnfs_get_layout_stateid is also slightly changed, so that\nit no longer changes the stateid.  Its name is changed to +pnfs_choose_layoutget_stateid.\n\nSigned-off-by: Fred Isaman \u003ciisaman@netapp.com\u003e\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n",
