From 35c7bfbcd4fabded090e5ab316a1cbf053a0a980 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Wed, 6 Mar 2013 23:39:38 -0600 Subject: [PATCH] libceph: advance pagelist with list_rotate_left() While processing an outgoing pagelist (either the data pagelist or trail) in a ceph message, the messenger cycles through each of the pages on the list. This is accomplished in out_msg_pos_next(), if the end of the first page on the list is reached, the first page is moved to the end of the list. There is a list operation, list_rotate_left(), which performs exactly this operation, and by using it, what's really going on becomes more obvious. So replace these two list_move_tail() calls with list_rotate_left(). Signed-off-by: Alex Elder Reviewed-by: Josh Durgin --- Reading git-format-patch failed
