Improve write caching behaviour for removable devices
Registered by

Use a new write cache mode for removable drives which combines the performance of write caching ("async" mode) with the intuitive and saver behaviour of the "sync" mode. Sync mode is inappropriate because it is unacceptably slow and has a fast flash wearout, while async mode takes a long time to flush the cache after unmounting, which caused us to add mitigations like "please do not remove" notifications.
Ideally write caching stays enabled, but the cache is flushed already when closing a file, not when unmounting a drive.
