Subject: [PATCH 13/14] staging: lustre: replace LIBCFS_CPT_ALLOC()
LIBCFS_APT_ALLOC() calls kvmalloc_node() with GFP_NOFS
which is not permitted.
Mostly, a kmalloc_node(GFP_NOFS) is appropriate, though occasionally
the allocation is large and GFP_KERNEL is acceptable, so
kvmalloc_node() can be used.
This patch introduces 4 alternatives to LIBCFS_CPT_ALLOC():
kmalloc_cpt()
kzalloc_cpt()
kvmalloc_cpt()
kvzalloc_cpt().
Each takes a size, gfp flags, and cpt number.
Almost every call to LIBCFS_CPT_ALLOC() passes lnet_cpt_table()
as the table. This patch embeds that choice in the k*alloc_cpt()
macros, and opencode kzalloc_node(..., cfs_cpt_spread_node(..))
in the one case that lnet_cpt_table() isn't used.
When LIBCFS_CPT_ALLOC() is replaced, the matching LIBCFS_FREE()
is also replaced, with with kfree() or kvfree() as appropriate.
