• 3cb030020   md: removing typedefs: mdk_rdev_t -> struct md_rdev ... Browse Code »

  The typedefs are just annoying. 'mdk' probably refers to 'md_k.h'
  which used to be an include file that defined this thing.

• 1b6afa175   md/linear: avoid corrupting structure while waiting for rcu_free to complete. ... Browse Code »

  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.

• 495d35730   md/linear: use call_rcu to free obsolete 'conf' structures. ... Browse Code »

  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.

• 4db7cdc85   md: Removing num_sector and replacing start_sector with end_sector ... Browse Code »

  Remove num_sectors from dev_info and replace start_sector with
  end_sector. This makes a lot of comparisons much simpler.

• 45d4582f2   md: Removal of hash table in linear raid ... Browse Code »

  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.

• 070ec55d0   md: remove mddev_to_conf "helper" macro ... Browse Code »

  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.

• bff61975b   md: move lots of #include lines out of .h files and into .c ... Browse Code »

  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.

  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.
