Make the recovery functions static to fix the following sparse warnings: lib/raid6/recov.c:25:6: warning: symbol 'raid6_2data_recov_intx1' was not declared. Should it be static? lib/raid6/recov.c:69:6: warning: symbol 'raid6_datap_recov_intx1' was not declared. Should it be static? lib/raid6/recov_ssse3.c:22:6: warning: symbol 'raid6_2data_recov_ssse3' was not declared. Should it be static? lib/raid6/recov_ssse3.c:197:6: warning: symbol 'raid6_datap_recov_ssse3' was not declared. Should it be static?

2012-05-22lib/raid6: cleanup gen_syndrome function selectionJim Kukunas1-47/+57
Reorders functions in raid6_algos as well as the preference check to reduce the number of functions tested on initialization. Also, creates symmetry between choosing the gen_syndrome functions and choosing the recovery functions.

2011-10-31md: Add in export.h for files using EXPORT_SYMBOLPaul Gortmaker2-0/+2
These files were getting the defines for EXPORT_SYMBOL because device.h was including module.h. But we are going to put an end to that. So add the proper export.h include now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31md: Add module.h to all files using it implicitlyPaul Gortmaker1-0/+1
A pending cleanup will mean that module.h won't be implicitly everywhere anymore. Make sure the modular drivers in md dir are actually calling out for <module.h> explicitly in advance. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
