Hi Willem,
As you described in the report you sent directly to us there are indeed
more issues than the one described here surrounding the kernfs node
reference counting in resctrl. Xiaochen is actively working on patch(es)
for all the issues and you could continue working with him
From: Willem de Bruijn
Resctrl takes an extra kernfs ref on directory entries, to access
the entry on cleanup in rdtgroup_kn_unlock after removing the entire
subtree with kfree_remove.
But the path takes an extra ref both on mkdir and on rmdir.
The kernfs_get on mkdir causes a memleak in the
3 matches
