Subject[PATCH v2 00/25] staging: lustre: libcfs: SMP rework
Date
From: James Simmons <uja.ornl@yahoo.com>

Recently lustre support has been expanded to extreme machines with as
many as a 1000+ cores. On the other end lustre also has been ported
to platforms like ARM and KNL which have uniquie NUMA and core setup.
For example some devices exist that have NUMA nodes with no cores.
With these new platforms the limitations of the Lustre's SMP code
came to light so a lot of work was needed. This resulted in this
patch set which has been tested on these platforms.

Amir Shehata (8):
staging: lustre: libcfs: replace MAX_NUMNODES with nr_node_ids
staging: lustre: libcfs: remove excess space
staging: lustre: libcfs: replace num_possible_cpus() with nr_cpu_ids
staging: lustre: libcfs: NUMA support
staging: lustre: libcfs: add cpu distance handling
staging: lustre: libcfs: use distance in cpu and node handling
staging: lustre: libcfs: provide debugfs files for distance handling
staging: lustre: libcfs: invert error handling for cfs_cpt_table_print

Dmitry Eremin (15):
staging: lustre: libcfs: remove useless CPU partition code
staging: lustre: libcfs: rename variable i to cpu
staging: lustre: libcfs: fix libcfs_cpu coding style
staging: lustre: libcfs: use int type for CPT identification.
staging: lustre: libcfs: rename i to node for cfs_cpt_set_nodemask
staging: lustre: libcfs: rename i to cpu for cfs_cpt_bind
staging: lustre: libcfs: rename cpumask_var_t variables to *_mask
staging: lustre: libcfs: rename goto label in cfs_cpt_table_print
staging: lustre: libcfs: update debug messages
staging: lustre: libcfs: make tolerant to offline CPUs and empty NUMA nodes
staging: lustre: libcfs: report NUMA node instead of just node
staging: lustre: libcfs: update debug messages in CPT code
staging: lustre: libcfs: rework CPU pattern parsing code
staging: lustre: libcfs: change CPT estimate algorithm
staging: lustre: ptlrpc: use current CPU instead of hardcoded 0

James Simmons (2):
staging: lustre: libcfs: restore UMP handling
staging: lustre: libcfs: properly handle failure cases in SMP code
