<enrico> richardb: how about fdatasync?
<richardb> ?
<enrico> richardb: uh, sorry, I just noticed I was reading an IRC discussion of yesterday
<richardb> heh
<enrico> richardb: I wrote that after reading "richardb> ext3 is bad enough (because whenever xapian calls fsync on a file, the whole filesystem gets synced."
 richardb: but it was more my curiosoty than a suggestion
<richardb> We use fdatasync when it's supported.
 Which is most linuxes, if not all, I think.
 Maybe fdatasync avoids the problem of flushing the whole filesystem, so it's not actually a problem.
 Not really that into filesystems, personally.
<tomeu> nice, I'll check with strace if we are actually using fdatasync
