Subject[PATCH v2 1/5] staging: lustre: obdclass: Create a header for obdo related functions
Date
From: Ben Evans <bevans@cray.com>

Remove all obdo related functions from lustre_idl.h
Create lustre_odbo.h. Include where appropriate.
Make the functions lustre_get_wire_obdo and
lustre_set_wire_obdo to not be inlined functions.
