[lustre-devel] [PATCH 00/10] lustre: lnet: fixes for non-x86 systems

[James Simmons <jsimmons@infradead.org>]

These are the required patches to make LNet work with non-x86
platforms like ARM or Power8. The tunables map_on_demand and
concurrent_sends assumed pages were 4K in size which is not
correct. Massively reworked to basically defunct those tunables.
Also the size of the LNet packet was always 256 pages but when
the page size is 64K like some ARM or Power8 systems the maximum
LNet message sent was 16MB not 1MB which is what is expected.
Fixing up the RDMA handling in the ko2iblnd driver also resolved
some performance issues.
