[green]

[PATCH 16/56] staging/lustre: Get rid of object update code

[green]

From: Oleg Drokin <green@linuxhacker.ru>

Object update was originally planned to be used for cross-server
updates, so nothing to do with the client. The idea was
later significantly reworked anyway so even wire structs should
not be retained.

This gets rid of update_cmd_t, UPDATE and UPDATE_REPLY rpc and
corresponding subcommands, swabbing logic and such.

[PATCH 24/56] staging/lustre: Remove lustre_build_version.h

[green]

From: Oleg Drokin <green@linuxhacker.ru>

of the two macroses is contained the LUSTRE_RELEASE was unused and
BUILD_VERSION is too generically named and was replaced with
LUSTRE_VERSION_STRING with all the users (provided by lustre_ver.h)

With in-kernel client the build version should be combined with
kernel build information anyway.

[PATCH 25/56] staging/lustre: Get rid of C99 comments in lustre_idl.h

[green]

From: Oleg Drokin <green@linuxhacker.ru>

lustre_idl.h contains various protocol data. In order to avoid
reusal of values that might have meant something else in the past,
the old no longer used values are commented out, convert the
comments into regular comments from C99 where appropriate.

[PATCH 35/56] staging/lustre: Remove index file transfer structures

[green]

From: Oleg Drokin <green@linuxhacker.ru>

struct idx_info, struct lu_idxpage, lustre_swab_idx_info,
request formats and related defines are all unused and could
only happen for between-servers communications, so remove them
from the client code.

[PATCH 36/56] staging/lustre: Remove server data from struct obd_export

[green]

From: Oleg Drokin <green@linuxhacker.ru>

Despite it's name struct obd_export could exist on the client too
(used for reverse exports), but all the actual server bits
are not needed there, so could be dropped. This is mostly
various target-related stuff.

[PATCH 37/56] staging/lustre: Remove last_rcvd-file related data

[green]

From: Oleg Drokin <green@linuxhacker.ru>

last_rcvd (last received) is a special server-side file on the
Lustre FS that stores information about server filesystem and
also list of connected clients and their state. There's no
point in having any of tha ton the client, though.

[PATCH 42/56] staging/lustre/include: Adjust comment style

[green]

From: Oleg Drokin <green@linuxhacker.ru>

This fixes most of the
"Block comments use a trailing */ on a separate line" checkpatch
warnings, also some slight reformats of structures or comments
at places.
