The rules above the line deal with the case where the goto desination is
the same whether or not the the branch is taken. In that case, the goto is
created in just one instance after the if. This affects only the files
namei.c and llite_lib.c.

44779340c6dcb8c858955c02b3aeef7d6b28a684 27-Apr-2014 Brian Behlendorf <behlendorf1@llnl.gov> staging/lustre: Limit reply buffer size

When allocating a reply buffer for the striping information don't
assume the unlikely worst case. Instead, assume the common case
and size the buffer based on the observed default ea/cookie size.

The default size is initialized to a single stripe and allowed to
grow up to an entire page if needed. This means that for smallish
filesystems (less than ~21 OSTs) where the worst case striping
information can fit in a single page there is effectively no
change. Only for larger filesystem will the default be less than
the maximum. This has a number of advantages.

* By limiting the default reply buffer size we avoid always
vmalloc()'ing the buffer because it exceeds four pages in size
and instead kmalloc() it. This prevents the client from
thrashing on the global vmalloc() spin lock.

* A reply buffer of exactly the right size (no larger) is allocated
in the overflow case. These larger reply buffers are still
unlikely to exceed the 16k limit where a vmalloc() will occur.

* Saves memory in the common case. Wide striped files exceeded
the default are expected to be the exception.

The reason this patch works is because the ptlrpc layer is smart
enough to reallocate the reply buffer when an overflow occurs.
Therefore the client doesn't have to drop the incoming reply and
send a new request with a larger reply buffer.

It's also worth mentioning that the reply buffer always contains
a significant amount of extra padding because they are rounded up
to the nearest power of two. This means that even files striped
wider than the default have a good chance of fitting in the
allocated reply buffer.

Also remove client eadatasize check in mdt xattr packing because
as said above client can handle -EOVERFLOW.

Lustre lprocfs depends heavily on it and its now-gone read_proc_t and
write_proc_t members.

The patch largely changed the fact, and made lprocfs depend on none of
proc_dir_entry private members. All lprocfs callers are converted to
use the new seq_file scheme.

Also lprocfs_srch is removed so that we can drop lprocfs_lock. All callers
are changed to save created pde in proper place.

See https://jira.hpdd.intel.com/browse/LU-3319 for more details.

d7e09d0397e84eefbabfd9cb353221f3c6448d83 02-May-2013 Peng Tao <bergwolf@gmail.com> staging: add Lustre file system client support

Lustre is the most deployed distributed file system
in the HPC (High Performance Computing) world. The patch
adds its client side support.

The code is not very clean and needs to live in drivers/staging
for some time for continuing cleanup work. See
drivers/staging/lustre/TODO for details.

The code is based on Lustre master commit faefbfc04

[maked the Kconfig depend on BROKEN as the recent procfs changes causes
this to fail - gregkh]
