The patch is a bit involved to ensure no additional impact on the memory footprint. The size of ocfs2_inode_cache remains 1280 bytes on 32-bit systems. A related change was to modify the unit of the max wait time from nanosec to microsec allowing us to track max time larger than 4 secs. This change necessitated the bumping of the output version in the debugfs file, locking_state, from 2 to 3. Signed-off-by: Sunil Mushran Signed-off-by: Joel Becker --- Reading git-diff-tree failed
