This patch tries to speedup fzero_range by making space preallocation and
address removal of blocks in one dnode page as in batch operation.
In virtual machine, with zram driver:

This patch introduces reserve_new_blocks to make preallocation of multi
blocks as in batch operation, so it can avoid lots of redundant
operation, result in better performance.

atomic/volatile ioctl interfaces are exposed to user like other file
operation interface, it needs to make them getting exclusion against
to each other to avoid potential conflict among these operations
in concurrent scenario.

In interfaces of ioctl, mnt_{want,drop}_write_file should be used for:
- get exclusion against file system freezing which may used by lvm
snapshot.
- do telling filesystem that a write is about to be performed on it, and
make sure that the writes are permitted.

The regulators set consists of 2 BUCKs and 2 LDOs. The output
voltages are configurable and are meant to supply power to the
main processor and other components. The ramp delay is configurable
for both BUCKs.

When this flag is set, we program the hardware to execute the flip
during horizontal blank (i.e. for the next scanline) instead of during
vertical blank (i.e. for the next frame).

In some case, this will result vm fault, like jobs with different vmids.

ib.vm is a legacy way to get vm, after scheduler
implemented vm should be get from job, and all ibs
from one job share the same vm, no need to keep ib.vm
just move vm field to job.
this patch as well add job as paramter to ib_schedule
so it can get vm from job->vm.
v2: agd: sqaush in:
