* Normalize a significant number of kernel malloc type names:rwatson2005-10-311-1/+1
| | | | | | | | | | | | | | | | | | | - Prefer '_' to ' ', as it results in more easily parsed results in memory monitoring tools such as vmstat. - Remove punctuation that is incompatible with using memory type names as file names, such as '/' characters. - Disambiguate some collisions by adding subsystem prefixes to some memory types. - Generally prefer lower case to upper case. - If the same type is defined in multiple architecture directories, attempt to use the same name in additional cases. Not all instances were caught in this change, so more work is required to finish this conversion. Similar changes are required for UMA zone names.

| | | | | | | | | | | | | | | | | shared-last-sector problem. After this change, even if there is more than one provider with the same last sector, the proper one will be chosen based on its size. It still doesn't fix the 'c' partition problem (when da0s1 can be confused with da0s1c) and situation when 'a' partition starts at offset 0 (then da0s1a can be confused with da0s1 and da0s1c). One can use '-h' option there, when creating device or avoid sharing last sector. Actually, when providers share the same last sector and their size is equal, they provide exactly the same data, so the name (da0s1, da0s1a, da0s1c) isn't important at all. - Provide backward compatibility. - Update copyright's year.

* This is not needed anymore, it is forced in GEOM now.pjd2004-09-201-3/+0
| | | | | | | | | Actually, it can even cause some problems, because GEOM requires sectorsize to be more than 0 on first access, not on provider creation, so we can skip valid providers by doing this check here.

* - Introduce option for hardcoding providers' names into metadata.pjd2004-08-092-1/+20
| | | | | | | | | | | | It allows to fix problems when last provider's sector is shared between few providers. - Bump version number for CONCAT and STRIPE and add code for backward compatibility. - Do not bump version number of MIRROR, as it wasn't officially introduced yet. Even if someone started to play with it, there is no big deal, because wrong MD5 sum of metadata will deny those providers. - Update manual pages. - Add version history to g_(stripe|concat).h files.
