Minchan Kim e7ccfc4ccb zram: revalidate disk under init_lock ... Commit b4c5c60920 ("zram: avoid lockdep splat by revalidate_disk") moved revalidate_disk call out of init_lock to avoid lockdep false-positive splat. However, commit 08eee69fcf ("zram: remove init_lock in zram_make_request") removed init_lock in IO path so there is no worry about lockdep splat. So, let's restore it. This patch is needed to set BDI_CAP_STABLE_WRITES atomically in next patch.
