cgroup/rdma: Drop bogus PAGE_COUNTER select

[PATCH next] cgroup/rdma: Drop bogus PAGE_COUNTER select

Posted by Geert Uytterhoeven 2 weeks, 6 days ago

When adding the Device memory controller (DMEM), "select PAGE_COUNTER"
was added to CGROUP_RDMA, presumably instead of CGROUP_DMEM.
While commit e33b51499a0a6bca ("cgroup/dmem: Select PAGE_COUNTER") added
the missing select to CGROUP_DMEM, the bogus select is still there.
Remove it.

Fixes: b168ed458ddecc17 ("kernel/cgroup: Add "dmem" memory accounting cgroup")
Closes: https://lore.kernel.org/CAMuHMdUmPfahsnZwx2iB5yfh8rjjW25LNcnYujNBgcKotUXBNg@mail.gmail.com
