+Description: Avoid deadlock for local client writes
+Details    : Use new OBD_BRW_MEMALLOC flag to notify OST about writes in the
+            memory freeing context. This allows OST threads to set the
+            PF_MEMALLOC flag on task structures in order to allocate memory
+            from reserved pools and complete IO.
+            Use GFP_HIGHUSER for OST allocations for non-local client writes,
+            so that the OST threads generate memory pressure and allow
+            inactive pages to be reclaimed.
