uuid: hoist uuid_is_null() helper from libnvdimm

2017-06-05T14:59:05+00:00

Hoist the libnvdimm helper as an inline helper to linux/uuid.h using an auxiliary const variable uuid_null in lib/uuid.c. [hch: also add the guid variant. Both do the same but I'd like to keep casts to a minimum] The common helper uses the new abstract type uuid_t * instead of u8 *.

uuid: don't export guid_index and uuid_index

2017-06-05T14:59:03+00:00

These are only used in uuid.c and vsprintf.c and aren't something modules should use directly. Signed-off-by: Christoph Hellwig Reviewed-by: Amir Goldstein Reviewed-by: Andy Shevchenko

uuid: rename uuid types

2017-06-05T14:58:59+00:00

Our "little endian" UUID really is a Wintel GUID, so rename it and its helpers such (guid_t). The big endian UUID is the only true one, so give it the name uuid_t. The uuid_le and uuid_be names are retained for now, but will hopefully go away soon. The exception to that are the _cmp helpers that will be replaced by better primitives ASAP and thus don't get the new names. Also the _to_bin helpers are named to match the better named uuid_parse routine in userspace. Also remove the existing typedef in XFS that's now been superceeded by the generic type name.

lib/uuid.c: use correct offset in uuid parser

2016-05-30T22:26:57+00:00

Use '+ 0' and '+ 1' as offsets, like they were intended, instead of adding to the result. Fixes: 2b1b0d66704a ("lib/uuid.c: introduce a few more generic helpers") Signed-off-by: Bjørn Mork Signed-off-by: Andy Shevchenko Signed-off-by: Linus Torvalds

lib/uuid.c: remove FSF address

There is no point in keeping an address in the file since it's subject to change. While here, update Intel Copyright years.

lib/uuid.c: introduce a few more generic helpers

2016-05-21T00:58:30+00:00

There are new helpers in this patch: uuid_is_valid checks if a UUID is valid uuid_be_to_bin converts from string to binary (big endian) uuid_le_to_bin converts from string to binary (little endian) They will be used in future, i.e. in the following patches in the series. This also moves the indices arrays to lib/uuid.c to be shared accross modules.

lib: reduce the use of module.h wherever possible

2012-03-07T20:04:04+00:00

For files only using THIS_MODULE and/or EXPORT_SYMBOL, map them onto including export.h -- or if the file isn't even using those, then just delete the include. Fix up any implicit include dependencies that were being masked by module.h along the way. Signed-off-by: Paul Gortmaker
