+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.

+ so that the OST threads generate memory pressure and allow
+ inactive pages to be reclaimed.
