From d2995737bb6da9fcb9f84bf820322e351df2813b Mon Sep 17 00:00:00 2001 From: "John L. Hammond" Date: Wed, 30 Mar 2016 19:48:34 -0400 Subject: [PATCH] staging/lustre/llite: remove lli_lvb In struct ll_inode_info remove the struct ost_lvb lli_lvb member and replace it with obd_time lli_{a,m,c}time. Rename ll_merge_lvb() to ll_merge_attr(). Remove cl_merge_lvb() and replace calls to it with calls to ll_merge_attr(). Signed-off-by: John L.
