Which conflicts with ours code:

So, as temporary fix restore old value for _PAGE_FILE.
If we care about supporting Xeon Phi we could backport
remap_file_pages() emulation from upstream which removes uses _PAGE_FILE.

The implementation is straightforward, since we already have per container
writeback. Sync just get user beancounter and launches writeback work for it.

Filter inodes before should happen befor the check for I_SYNC flag.
During per-container writeback we don't wan't to requeue inodes from
other containers.

since requeue_io() means that we will busy retry to write that inode.
redirty_tail() should be used to skip inodes.
