[Ocfs2-users] ocfs2 is still eating memory

[Sunil Mushran]

The core ocfs2 code is similar in both sles9 and sles10. Yes, there are
some differences based upon the differing hb options, but the core fs,
dlm code is the same. Well, as in, sles9 sp3 2.6.5-7.283 is ocfs2 1.2.3
and sles10 sp1 kotd is ocfs2 1.2.4.
