Christophe JAILLET 04102c76a7 orangefs: Axe some dead code
The "perf_counter_reset" case has already been handled above.
Moreover "ORANGEFS_PARAM_REQUEST_OP_READAHEAD_COUNT_SIZE" is not a really
consistent.
It is likely that this (dead) code is a cut and paste left over.

Martin Brandenburg 1d50361788 orangefs: rename most remaining global variables
Only op_timeout_secs, slot_timeout_secs, and hash_table_size are left
because they are exposed as module parameters. All other global
variables have the orangefs_ prefix.

Martin Brandenburg 2e9f80da07 orangefs: reorganize duplicated sysfs attribute structs
We had a separate struct type for each type of attribute, but they all
did the exact same thing. Consolidate them into one
struct orangefs_attribute type.

Martin Brandenburg dc3012a7af orangefs: remove dead code in sysfs
We had a pageful of structures containing kobjects and variables to store
sysfs entries. However only the kobjects were in use. Replace them with
kobjects.

Martin Brandenburg 680908e504 orangefs: turn param response value into union
This will support a upcoming request where two related values need to be
updated atomically.

This was done without a union in the OrangeFS server source already. Since
that will break the kernel protocol, it has been fixed there and done here
in a way that does not break the kernel protocol.

Al Viro ed42fe0593 orangefs: hopefully saner op refcounting and locking
* create with refcount 1
* make op_release() decrement and free if zero (i.e. old put_op()
  has become that).
* mark when submitter has given up waiting; from that point nobody
  else can move between the lists, change state, etc.
* have daemon read/write_iter grab a reference when picking op
  and *always* give it up in the end
* don't put into hash until we know it's been successfully passed to
  daemon

* move op->lock _lower_ than htab_in_progress_lock (and make sure
  to take it in purge_inprogress_ops())
