linux-next: build warning after merge of the vfs tree

[Stephen Rothwell]

Hi Al,

After merging the vfs tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c: In function 
'kiblnd_send':
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c:1643:2: warning: 
ignoring return value of 'copy_from_iter', declared with attribute 
warn_unused_result [-Wunused-result]
  copy_from_iter(&ibmsg->ibm_u.immediate.ibim_payload, IBLND_MSG_SIZE,
  ^
