staging: lustre: vvp: Use lockless __generic_file_aio_write

Testing multi-threaded single shard file write performance has shown
the inode mutex to be a limiting factor when using the
generic_file_write_iter function. To work around this bottle neck, this
change replaces the locked version of that call with the lock less
version, specifically, __generic_file_write_iter.

In order to maintain posix consistency, Lustre must now employ it's
own locking mechanism in the higher layers. Currently writes are
protected using the lli_write_mutex in the ll_inode_info structure.
To protect against simultaneous write and truncate operations, since
we no longer take the inode mutex during writes, we must down the
lli_trunc_sem semaphore.

Unfortunately, this change by itself does not garner any performance
benefits. Using FIO on a single machine with 32 GB of RAM, write
performance tests were ran with and without this change applied; the
results are below:

In order to garner any real performance benefits out of a single
shared file workload, the lli_write_mutex needs to be broken up into a
range lock. That would allow write operations to unique regions of a

While clients will resend client->server RPCs, servers would not

 - still do not resend CANCEL_ON_BLOCK;
 - regular resend for CP AST without BL AST embedded;
 - prolong lock callback timeout on resend;

some fixes:

Staging: ks7010: Replace memset with eth_zero_addr

Use eth_zero_addr to assign zero address to the given address array
instead of memset when the second argument in memset is address
of zero. Coccinelle was used to do the replacement and add the
header file linux/etherdevice.h if not already present.
Script:
@header@

#include <linux/etherdevice.h>

@r1@

-memset(e,0,ETH_ALEN);
+eth_zero_addr(e);

@includeheader depends on r1 && !header@

staging: wilc1000: Use sizeof type *pointer instead of sizeof type

The patch uses the size of the dereference to a variable instead of it's type,
to make the code more resistant to type changes in the future. The type of the
pointer variable here is the same as the type in the argument that is being
replaced in sizeof().
