LU-169 lov: add generation number to LOV EA

This patch shrinks lov_mds_md_v*::lmm_stripe_count to 16 bits and use
the remaining 16 bits to store a generation number for the layout.
This generation will be used in conjunction the layout lock to allow
clients to detect when the file layout has changed.
The layout generation starts at 0 and will be bumped each time the
file layout is altered.
For backward compatibility, the layout generation is set to 0 when the
layout is sent to a client that does not support
OBD_CONNECT_LAYOUTLOCK.

This patch also stores OBD_INCOMPAT_LMM_VER in the MDS last_rcvd file
to prevent older versions of Lustre that cannot deal with a 16-bit
lmm_stripe from mounting the filesystem and exporting layouts to older
clients without setting the layout to 0.  This flag will be set in the
last_rcvd file only once we start modifying file layouts, but at least
the current version should not be confused by a 16-bit stripe count
and a non-zero generation.

shell "while" command.  Though this is done in the current
environment (process) for current BASH, it is not required

this way.  Instead, set fd 3 to be reading from that file
and read from fd 3 insted of stdin.

While there, also test for "is object id" lines and extract
values using shell constructs instead of fork-ed commands.

Also while there, ensure that "ERROR" is always printed on
every error exit.

Also while there, ensure that the libecho file comes from
the same directory as the obdfilter-survey script.

Andreas Dilger [Thu, 27 Oct 2011 00:59:15 +0000 (18:59 -0600)]
LU-794 llite: allow larger O_DIRECT read/write RPC

The O_DIRECT read/write RPC size limit was formerly constrained by
the maximum kmalloc() size, and would fall back to smaller kmalloc()
allocations until they succeeded.  This constrained the number of
concurrent O_DIRECT RPCs, which can significantly affect performance.

Newer code uses OBD_ALLOC_LARGE()  vmalloc() for allocations larger
than a page, so the maximum RPC limit can be increased.  Currently
the limit is arbitrarily set to KMALLOC_MAX_SIZE (which is just a
proxy for what is a reasonably large allocation is for the system).

This increases the maximum O_DIRECT limit to about 682MB, which will
allow sending 8 concurrent RPCs on an 85-stripe file with a single
write() or combination thereof.  This could be increased if needed.
