Further questions: Why do you do your own refcounting instead of using kref?That's because I always used atomic operations as a reference counters and did not tried krefs :) They are the same actually (module tricky arches where smp_mb_* are required), so I can replace them in the next release.
Actually not - I have to set reference counter to something other than 1 or +/- 1, and thus will have to call kref_get() in a loop, which is a very ugly step. Is there kref_set() or somethinglike that? At least not in 2.6.22 what I'm using for now. Sigh, I've converted most of the DST already... -- Evgeniy Polyakov
