2011-10-11md/linear: typedef removal: linear_conf_t -> struct linear_confGravatar NeilBrown 1-5/+1
Signed-off-by: NeilBrown <neilb@suse.de>
2011-10-11md/linear: remove typedefs: dev_info_t -> struct dev_infoGravatar NeilBrown 1-3/+1

2011-10-11md: removing typedefs: mdk_rdev_t -> struct md_rdevGravatar NeilBrown 1-1/+1
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 <neilb@suse.de>
2011-08-25md/linear: avoid corrupting structure while waiting for rcu_free to complete.Gravatar NeilBrown 1-1/+1
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 <neilb@suse.de>
2009-06-18md/linear: use call_rcu to free obsolete 'conf' structures.Gravatar NeilBrown 1-1/+1
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 <neilb@suse.de>
2009-06-16md: Removing num_sector and replacing start_sector with end_sectorGravatar Sandeep K Sinha 1-2/+1
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 <sandeepksinha@gmail.com> Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-16md: Removal of hash table in linear raidGravatar Sandeep K Sinha 1-5/+0
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" macroGravatar NeilBrown 1-2/+0
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>
2009-03-31md: move lots of #include lines out of .h files and into .cGravatar NeilBrown 1-2/+0
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 <neilb@suse.de>
2009-03-31md: move headers out of include/linux/raid/Gravatar Christoph Hellwig 1-0/+31
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.
