Yeah, all good tweaks - thanks for catching those. And thanks for carrying
the ocfs2 patch in -mm.

Hmm, should we fix up touch_atime() to use "<=" as well? Maybe I didn't read

The logic I have there is the same (I hope)...

+ if (timespec_compare(&inode->i_mtime,

+ timespec_compare(&inode->i_ctime,
+ &inode->i_atime) < 0)
+ return;

Oh ok, yeah I didn't notice that the arguments to timespec_compare() had
