try calling `sysctl` after `sync` here :
(13:45) giovanni @ ~ $ sync; sudo sysctl vm.drop_caches=3
(13:45) giovanni @ ~ $ cat /run/media/giovanni/Data/mount_test.txt
Here is the result:
---
(17:17) giovanni @ ~ $ udisksctl mount -b /dev/nvme0n1p5 -t ntfs3
Mounted /dev/nvme0n1p5 at /run/media/giovanni/Data

Having to always run the sysctl command in order to force the flush
seems very bad to me...
So, again, sync alone does not work. sysctl then sync does not. sync and
then sysctl does...
But the sysctl command needs to be executed every time.
