bool SliceGetLocked (uint64_t vslice, uint64_t * out_pslice)Returns true if the respective |vslice| is mapped to a physical slice, and sets |*pslice| to
the mapped physical slice. Returns false if the |vslice| is unallocated.

zx_status_t CheckSlices (uint64_t vslice_start, size_t * count, bool * allocated)Check slices starting from |vslice_start|.
Sets |*count| to the number of contiguous allocated or unallocated slices found.
Sets |*allocated| to true if the vslice range is allocated, and false otherwise.
Defined at line 111 of file ../../src/storage/fvm/driver/vpartition.cc
void SliceSetLocked (uint64_t vslice, uint64_t pslice)Maps the respective |vslice| to the given |pslice| and it will be considered as allocated.

void SliceFreeLocked (uint64_t vslice)Marks |vslice| free from this partition. |vslice| is required to be allocated in the
partition, users should call SliceCanFree(vslice) before calling this method.
