[lustre-devel] [PATCH 07/24] lustre: ptlrpc: pass lnet_nid for self to ptl_send_buf()

[James Simmons <jsimmons@infradead.org>]

From: Mr NeilBrown <neilb@suse.de>

The 'self' arg to ptl_send_buf() is now a pointer to a
'struct lnet_nid', and can be NULL meaning "ANY NID".

LNetPut() already accepts NULL as the self pointer.

WC-bug-id: https://jira.whamcloud.com/browse/LU-10391
