From 49126e47bf418081a4eb3686a8c736ca80da152c Mon Sep 17 00:00:00 2001 From: Xiong Zhou Date: Fri, 2 Aug 2013 13:50:48 +0800 Subject: [PATCH] staging/lustre: lloop depends on BLOCK MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a config option for llite/lloop in lustre driver, making it depends on BLOCK to fix this better: drivers/staging/lustre/lustre/fid/../include/linux/lustre_compat25.h:117:2: error: implicit declaration of function ‘unregister_blkdev' Also, remove the wrapper ll_unregister_blkdev which depends on BLOCK in the header and just call unregister_blkdev in lloop.c based on Peng Tao's comment. Drop the redundant dependency on STAGING for LUSTRE_FS, remove some unnecessary jdb header files which depends on BLOCK btw.
