md: removing typedefs: mdk_rdev_t -> struct md_rdev

2011-10-11T05:45:26Z

The typedefs are just annoying. 'mdk' probably refers to 'md_k.h' which used to be an include file that defined this thing. Signed-off-by: NeilBrown

md/linear: avoid corrupting structure while waiting for rcu_free to complete.

2011-08-25T04:43:53Z

I don't know what I was thinking putting 'rcu' after a dynamically sized array! The array could still be in use when we call rcu_free() (That is the point) so we mustn't corrupt it. Cc: stable@kernel.org Signed-off-by: NeilBrown

md/linear: use call_rcu to free obsolete 'conf' structures.

2009-06-17T22:49:42Z

Current, when we update the 'conf' structure, when adding a drive to a linear array, we keep the old version around until the array is finally stopped, as it is not safe to free it immediately. Now that we have rcu protection on all accesses to 'conf', we can use call_rcu to free it more promptly. Signed-off-by: NeilBrown

md: Removing num_sector and replacing start_sector with end_sector

2009-06-16T06:56:13Z

Remove num_sectors from dev_info and replace start_sector with end_sector. This makes a lot of comparisons much simpler. Signed-off-by: Sandeep K Sinha Signed-off-by: NeilBrown

md: Removal of hash table in linear raid

2009-06-16T06:55:26Z

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. Signed-off-by: Sandeep K Sinha Signed-off-by: NeilBrown

md: remove mddev_to_conf "helper" macro

2009-06-16T06:54:21Z

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

md: move lots of #include lines out of .h files and into .c

2009-03-31T03:33:13Z

This makes the includes more explicit, and is preparation for moving md_k.h to drivers/md/md.h Remove include/raid/md.h as its only remaining use was to #include other files. Signed-off-by: NeilBrown

md: move headers out of include/linux/raid/

2009-03-31T03:27:03Z

Move the headers with the local structures for the disciplines and bitmap.h into drivers/md/ so that they are more easily grepable for hacking and not far away. md.h is left where it is for now as there are some uses from the outside. Signed-off-by: Christoph Hellwig Signed-off-by: NeilBrown
