VPartitionEntry * GetAllocatedVPartEntry (size_t index)

Acquire access to a VPart Entry which has already been modified (and

will, as a consequence, not be de-allocated underneath us).

header from inside the lock.

Read the underlying block device, initialize the recorded VPartitions.

zx_status_t AllocateSlices (VPartition * vp, size_t vslice_start, size_t count)

Allocate 'count' slices, write back the FVM.

zx_status_t FreeSlices (VPartition * vp, size_t vslice_start, size_t count)

Deallocate 'count' slices, write back the FVM.

If a request is made to remove vslice_count = 0, deallocates the entire

VPartition.

Allocates the partition, returning it without adding it to the device manager. Production code

will go through the FIDL API, this is exposed separately to allow testing without FIDL.
