This function adds __GFP_WAIT to all flags except CFS_ALLOC_ATOMIC. In 2.5, when the cfs wrappers were dropped, cfs_alloc_flags_to_gfp() was removed and the CFS_ALLOC_xxxx was simply replaced with __GFP_xxxx. This means that most memory allocation calls are missing the __GFP_WAIT flag. The result is that Lustre experiences more ENOMEM errors, many of which the higher levels of Lustre do not handle robustly. Notes GFP_NOFS = __GFP_WAIT | __GFP_IO. So the patch replaces __GFP_IO with GFP_NOFS. Patch does not add __GFP_WAIT to GFP_IOFS. GFP_IOFS was not used in Lustre 2.4 so it has never been used with __GFP_WAIT.
