linux-toradex.git/fs/ocfs2/move_extents.h, branch v3.0.64 Linux kernel for Apalis and Colibri modules Ocfs2/move_extents: move/defrag extents within a certain range. 2011-05-25T07:17:12+00:00 Tristan Ye tristan.ye@oracle.com 2011-05-25T06:23:43+00:00 53069d4e76954e2e63c1b3c501051c6fbcf7298c the basic logic of moving extents for a file is pretty like punching-hole sequence, walk the extents within the range as user specified, calculating an appropriate len to defrag/move, then let ocfs2_defrag/move_extent() to do the actual moving. This func ends up setting 'OCFS2_MOVE_EXT_FL_COMPLETE' to userpace if operation gets done successfully. Signed-off-by: Tristan Ye <tristan.ye@oracle.com>
