Agreed. > Can someone shows me a valid use case of sync on tmpfs? Unlikely. The last time I checked sync is a no-op on ramfs and tmpfs anyway (shmem.c). Also, tmpfs would not write out to swap on sync. Likewise, as there is no point of syncing anything if a on-disk filesystem is mounted read-only, hence kernel does not even bother to (sync.c). -- pub 4096R/0E4BD0AB <people.fccf.net/danchev/key pgp.mit.edu> -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
