2014-04-27staging/lustre: restore __GFP_WAIT flag to memalloc callsAnn Koehler
In Lustre 2.4, the flags passed to the memory allocation functions are translated from CFS enumeration values types to the kernel GFP values by calling cfs_alloc_flags_to_gfp(). 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.

2014-02-07lustre: Correct KUC code max changelog msg sizeOleg Drokin
The kernel to userspace communication routines (KUC) allocate and limit the maximum cs_buf size to CR_MAXSIZE. However this fails to account for the fact that the buffer is assumed to begin with a struct kuc_hdr. To allocate and account for that space, we introduce a new define, KUC_CHANGELOG_MSG_MAXSIZE.
