• 550929faf   dm persistent data: rename node to btree_node ... Browse Code »

  This patch fixes a compilation failure on sparc32 by renaming struct node.

  struct node is already defined in include/linux/node.h. On sparc32, it
  happens to be included through other dependencies and persistent-data
  doesn't compile because of conflicting declarations.

• a3aefb395   dm persistent data: remove redundant value_size arg from value_ptr ... Browse Code »

  Now that the value_size is held within every node of the btrees we can
  remove this argument from value_ptr().

  For the last few months a BUG_ON has been checking this argument is
  the same as that held in the node. No issues were reported. So this
  is a safe change.

  The persistent-data library offers a re-usable framework for the storage
  and management of on-disk metadata in device-mapper targets.

  It's used by the thin-provisioning target in the next patch and in an
  upcoming hierarchical storage target.

  For further information, please read
  Documentation/device-mapper/persistent-data.txt
