fs: disable dynamic fsync

Some users reported data loss in some circumstances.
I guess we should enable fsync in any case, this
might decrease perfomance noticeable, but at least
we have data integrity.

mm: vmscan: fix possible deadlock

In some cases its possible that shrink_slab() tries to shrink negative objects of ashmem:
shrink_slab: ashmem_shrink+0x0/0xf8 negative objects to delete nr=-2147299715

This patch should fix it, not only for ashmem, but for all
who call shrink_slab.
