[PATCH 00/21] staging: assorted lustre clean-up

[NeilBrown]

Following are assorted patches which clean up parts of lustre.
One or two tiny buglets are fixed, but mostly the patches
just make the code more readable, often by removing distractions.

The first several patches remove content from libcfs, completely
removing 3 files.
There are some list_for_each improvements in ptlrpc, and some
code simplification in fid.
Finally a small simplification in socklnd.

(lnd ?? Lustre Networking Domain??)

Thanks,
NeilBrown
