Ocfs2/move_extents: Let defrag handle partial extent moving. Ocfs2/move_extents: move/defrag extents within a certain range. Ocfs2/move_extents: helper to calculate the defraging length in one run. Ocfs2/move_extents: move entire/partial extent. Ocfs2/move_extents: helpers to update the group descriptor and global bitmap inode. Ocfs2/move_extents: helper to probe a proper region to move in an alloc group. Ocfs2/move_extents: helper to validate and adjust moving goal. Ocfs2/move_extents: find the victim alloc group, where the given #blk fits. Ocfs2/move_extents: defrag a range of extent. Ocfs2/move_extents: move a range of extent. Ocfs2/move_extents: lock allocators and reserve metadata blocks and data clusters for extents moving. Ocfs2/move_extents: Add basic framework and source files for extent moving. Ocfs2/move_extents: Adding new ioctl code 'OCFS2_IOC_MOVE_EXT' to ocfs2. Ocfs2/refcounttree: Publicize couple of funcs from refcounttree.c Ocfs2: Add a new code 'OCFS2_INFO_FREEFRAG' for o2info ioctl. Ocfs2: Add a new code 'OCFS2_INFO_FREEINODE' for o2info ioctl. ...
