Inode is owned only by one memory cgroup, but if it's shared it might
contain pages from multiple cgroups. This patch detects this situation
in memory reclaiemer and marks dirty inode with flag I_DIRTY_SHARED
which is cleared only when data is completely written. Memcg writeback
always writes such inodes.

Signed-off-by: Konstantin Khlebnikov <redacted>

This conflicts with the writeback cgroup support patchset which will
solve the writeback and memcg problem a lot more comprehensively.
