* dm persistent data: add btree_walkJoe Thornber2013-03-011-0/+1
| | | | | | | | Add dm_btree_walk to iterate through the contents of a btree. This will be used by the dm cache target. Signed-off-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
* dm persistent data: rename node to btree_nodeMikulas Patocka2012-12-211-8/+8
| | | | | | | | | | | | 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.

* dm persistent data: remove redundant value_size arg from value_ptrJoe Thornber2012-03-281-5/+2
| | | | | | | | | | | | | 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.

* dm: add persistent data libraryJoe Thornber2011-10-311-0/+137
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.
