Subject: [PATCH] zram: clear IDLE flag in mark_idle()
If entry does not fulfill current mark_idle() parameters, e.g. cutoff time, then we should clear its ZRAM_IDLE from previous mark_idle() invocations.
Consider the following case:
- mark_idle() cutoff time 8h
- mark_idle() cutoff time 4h
- writeback() idle - will writeback entries with cutoff time 8h, while it should only pick entries with cutoff time 4h
The bug was reported by Shin Kawamura.
