[0/3] remove tmem and code depending on it

Message

Jürgen Groß May 27, 2019, 10:32 a.m. UTC

Tmem has been an experimental Xen feature which has been dropped
recently due to security problems and lack of maintainership.

So it is time now to drop it in Linux kernel, too.

Juergen Gross (3):
  xen: remove tmem driver
  mm: remove cleancache.c
  mm: remove tmem specifics from frontswap
