From f701d589aa34d7531183c9ac6f7713ba14212b02 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Tue, 31 Mar 2009 15:09:39 +1100 Subject: md/raid6: move raid6 data processing to raid6_pq.ko Move the raid6 data processing routines into a standalone module (raid6_pq) to prepare them to be called from async_tx wrappers and other non-md drivers/modules. This precludes a circular dependency of raid456 needing the async modules for data processing while those modules in turn depend on raid456 for the base level synchronous raid6 routines. To support this move: 1/ The exportable definitions in raid6.h move to include/linux/raid/pq.h 2/ The raid6_call, recovery calls, and table symbols are exported 3/ Extra #ifdef __KERNEL__ statements to enable the userspace raid6test to compile Signed-off-by: Dan Williams Signed-off-by: NeilBrown --- drivers/md/raid6recov.c | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) (limited to 'drivers/md/raid6recov.c') diff --git a/drivers/md/raid6recov.c b/drivers/md/raid6recov.c index 7a98b865258..2609f00e0d6 100644 --- a/drivers/md/raid6recov.c +++ b/drivers/md/raid6recov.c @@ -18,7 +18,7 @@ * the syndrome.) */ -#include "raid6.h" +#include /* Recover two failed data blocks. */ void raid6_2data_recov(int disks, size_t bytes, int faila, int failb, @@ -63,9 +63,7 @@ void raid6_2data_recov(int disks, size_t bytes, int faila, int failb, p++; q++; } } - - - +EXPORT_SYMBOL_GPL(raid6_2data_recov); /* Recover failure of one data block plus the P block */ void raid6_datap_recov(int disks, size_t bytes, int faila, void **ptrs) @@ -97,9 +95,10 @@ void raid6_datap_recov(int disks, size_t bytes, int faila, void **ptrs) q++; dq++; } } +EXPORT_SYMBOL_GPL(raid6_datap_recov); - -#ifndef __KERNEL__ /* Testing only */ +#ifndef __KERNEL__ +/* Testing only */ /* Recover two failed blocks. */ void raid6_dual_recov(int disks, size_t bytes, int faila, int failb, void **ptrs) -- cgit v1.2.3
