From ad88aae057b9f952f1cbd2f5df8325b95ba7bb75 Mon Sep 17 00:00:00 2001 From: Oleg Drokin Date: Sat, 8 Aug 2015 20:09:06 -0400 Subject: [PATCH] staging/lustre/llite: get rid of unused ll_super_blocks list ll_super_blocks became unused quite a while ago with switch to the new CLIO code. So this patch removes the list, ll_sb_lock spinlock that guards it and superblock info ll_list linkage.
