Section 12.7.4 says:

      If the metadata server's
      consistency checks on loca_layoutupdate succeed, then the metadata
      server MUST commit the data (as described by the loca_offset,
      loca_length, and loca_layoutupdate fields of the arguments) that
      was written to the storage device. If the metadata server's
      consistency checks on loca_layoutupdate fail, the metadata server
      rejects the LAYOUTCOMMIT operation and makes no changes to the
      file system.  However, any time LAYOUTCOMMIT with loca_reclaim
      TRUE fails, the pNFS client has lost all the data in the range
      defined by <loca_offset, loca_length>.  

It should say:

      If the metadata server's
      consistency checks on loca_layoutupdate succeed, then the metadata
      server MUST commit the changed data that was written to the storage
      device within the scope of the LAYOUTCOMMIT operation.
      If the metadata server's
      consistency checks on loca_layoutupdate fail, the metadata server
      rejects the LAYOUTCOMMIT operation and makes no changes to the
      file system.  However, any time LAYOUTCOMMIT with loca_reclaim
      TRUE fails, the pNFS client may have lost all uncommitted
	data within the scope of the failed LAYOUTCOMMIT operation.  

Notes:

Errata 2 of 5 to deprecate loca_offset and loca_length arguments to LAYOUTCOMMIT.
