Did you read the other other part of the description? Further, both functions can be used to accurately trace the refcount (refcount_inc() followed by refcount_read() can't be considered accurate). > If you'll remember, I did that for inode_count and only needed > dec_unless(). I don't remember. inode_count? I can't find such a thing - did you mean i_count? I don't find anything matching "dec_unless.*i_count" either. David
