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.

lustre: get rid of messing with iovecs
* switch to ->read_iter/->write_iter
* keep a pointer to iov_iter instead of iov/nr_segs
* do not modify iovecs; use iov_iter_truncate()/iov_iter_advance() and
a new primitive - iov_iter_reexpand() (expand previously truncated
iterator) istead.
* (racy) check for lustre VMAs intersecting with iovecs kept for now as
for_each_iov() loop.

staging/lustre/llite: remove lustre_generic_file_{read,write}
It looks like lustre_generic_file_{read,write} are a holdover from
2.6.19 where generic_file_aio_read() replaced generic_file_readv()
and cross-kernel interoperability was required for some period of
time. Lustre has since removed support for those older kernels, but
it looks like the wrappers were not deleted at that time. This patch
will delete them.
Pass &iocb->ki_pos as the last argument for these functions instead
of crw_pos, since this is the convention for other callers. Verify
that this is the same as the current crw_pos argument. This code can
likely be cleaned up further in a later patch.

staging/lustre: fix build error on non-x86 platforms
dump_trace() is only available on X86. Without it, Lustre's own
watchdog is broken. We can only dump current task's stack.
The client-side this code is much less likely to hit deadlocks and
it's probably OK to drop this altogether, since we hardly have any
ptlrpc threads on clients, most notable ones are ldlm cb threads
that should not really be blocking on the client anyway.
Remove libcfs watchdog for now, until the upstream kernel watchdog
can detect distributed deadlocks and dump other kernel threads.

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
commit faefbfc0460bc00f2ee4c1c1c86aa1e39b9eea49
