+* @name IncreaseMftSize

+*
+* @param Vcb
+* Pointer to the VCB (DEVICE_EXTENSION) of the target volume.
+*
+*
+* @param CanWait
+* Boolean indicating if the function is allowed to wait for exclusive access to the master file table.
+* This will only be relevant if the MFT doesn't have any free file records and needs to be enlarged.
+*
+* @return
+* STATUS_SUCCESS on success.
+* STATUS_INSUFFICIENT_RESOURCES if an allocation fails.
+* STATUS_INVALID_PARAMETER if there was an error reading the Mft's bitmap.
+* STATUS_CANT_WAIT if CanWait was FALSE and the function could not get immediate, exclusive access to the MFT.
+*
+* @remarks
+* Increases the size of the Master File Table by 8 records. Bitmap entries for the new records are cleared,
+* and the bitmap is also enlarged if needed. Mimicking Windows' behavior when enlarging the mft is still TODO.
+* This function will wait for exlusive access to the volume fcb.
