2009-06-16md: raid0: chunk size check in raid0_runraz ben yehuda
have raid0 check chunk size in run method instead of in md. This is part of a series moving the checks from common code to the personalities where they belong. hardsect is short and chunksize is an int, so it is safe to use %.

2009-06-16md: Removal of hash table in linear raidSandeep K Sinha
Get rid of sector_div and hash table for linear raid and replace with a linear search in which_dev. The hash table adds a lot of complexity for little if any gain. Ultimately a binary search will be used which will have smaller cache foot print, a similar number of memory access, and no divisions.

2009-06-16md: remove mddev_to_conf "helper" macroNeilBrown
Having a macro just to cast a void* isn't really helpful. I would must rather see that we are simply de-referencing ->private, than have to know what the macro does. So open code the macro everywhere and remove the pointless cast. Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-16md: raid0: remove setting of segment boundary.NeilBrown
This setting doesn't seem to make sense (half the chunk size??) and shouldn't be needed. The segment boundary exported by raid0 should simply be the minimum of the segment boundary of all component devices. And we already get that right. Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-16md: raid0: remove ->dev pointer from strip_zone structureNeilBrown
If we treat conf->devlist more like a 2 dimensional array, we can get the devlist for a particular zone simply by indexing that array, so we don't need to store the pointers to subarrays in strip_zone. This makes strip_zone smaller and so (hopefully) searches faster. Signed-of-by: NeilBrown <neilb@suse.de>
2009-06-16md: raid0: remove ->sectors from the strip_zone structure.NeilBrown
storing ->sectors is redundant as is can be computed from the difference z->zone_end - (z-1)->zone_end The one place where it is used, it is just as efficient to use a zone_end value instead. And removing it makes strip_zone smaller, so they array of these that is searched on every request has a better chance to say in cache. So discard the field and get the value from elsewhere. Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-16md: raid0: Fix a memory leak when stopping a raid0 array.Andre Noll
raid0_stop() removes all references to the raid0 configuration but misses to free the ->devlist buffer. This patch closes this leak, removes a pointless initialization and fixes a coding style issue in raid0_stop(). Signed-off-by: Andre Noll <maan@systemlinux.org> Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-16md: raid0: Allocate all buffers for the raid0 configuration in one function.Andre Noll
Currently the raid0 configuration is allocated in raid0_run() while the buffers for the strip_zone and the dev_list arrays are allocated in create_strip_zones(). On errors, all three buffers are freed in raid0_run(). It's easier and more readable to do the allocation and cleanup within a single function. So move that code into create_strip_zones(). Signed-off-by: Andre Noll <maan@systemlinux.org> Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-16md: raid0: Make raid0_run() return a proper error code.Andre Noll
Currently raid0_run() always returns -ENOMEM on errors. This is incorrect as running the array might fail for other reasons, for example because not all component devices were available. This patch changes create_strip_zones() so that it returns a proper error code (either -ENOMEM or -EINVAL) rather than 1 on errors and makes raid0_run(), its single caller, return that value instead of -ENOMEM.

2009-06-16md: raid0: Remove hash spacing and sector shift.Andre Noll
The "sector_shift" and "spacing" fields of struct raid0_private_data were only used for the hash table lookups. So the removal of the hash table allows get rid of these fields as well which simplifies create_strip_zones() and raid0_run() quite a bit. Signed-off-by: Andre Noll <maan@systemlinux.org> Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-16md: raid0: Remove hash table.Andre Noll
The raid0 hash table has become unused due to the changes in the previous patch. This patch removes the hash table allocation and setup code and kills the hash_table field of struct raid0_private_data. Signed-off-by: Andre Noll <maan@systemlinux.org> Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-16md/raid0: two cleanups in create_stripe_zones.NeilBrown
1/ remove current_start. The same value is available in zone->dev_start and storing it separately doesn't gain anything. 2/ rename curr_zone_start to curr_zone_end as we are now more focused on the 'end' of each zone. We end up storing the same number though - the old name was a little confusing (and what does 'current' mean in this context anyway). Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-16md: raid0: Replace hash table lookup by looping over all strip_zones.Andre Noll
The number of strip_zones of a raid0 array is bounded by the number of drives in the array and is in fact much smaller for typical setups. For example, any raid0 array containing identical disks will have only a single strip_zone. Therefore, the hash tables which are used for quickly finding the strip_zone that holds a particular sector are of questionable value and add quite a bit of unnecessary complexity. This patch replaces the hash table lookup by equivalent code which simply loops over all strip zones to find the zone that holds the given sector. In order to make this loop as fast as possible, the zone->start field of struct strip_zone has been renamed to zone_end, and it now stores the beginning of the next zone in sectors. This allows to save one addition in the loop. Subsequent cleanup patches will remove the hash table structure.
