ocfs2: track local alloc state via debugfs
A per-mount debugfs file, "local_alloc" is created which when read will expose live state of the nodes local alloc file. Performance impact is minimal, only a bit of memory overhead per mount point. Still, the code is hidden behind CONFIG_OCFS2_FS_STATS. This feature will help us debug local alloc performance problems on a live system. Signed-off-by: Mark Fasheh <mfasheh@suse.com>
