[lustre-devel] [PATCH 000/622] lustre: sync closely to 2.13.52

[James Simmons <jsimmons@infradead.org>]

These patches need to be applied to the lustre-backport branch
starting at commit a436653f641e4b3e2841f38113620535e918dd3f.
Combining the work of Neil and myself this brings the lustre
linux client up to just btefore the he landing of Direct I/O
(LU-4198) support. Testing shows this work is pretty stable.
