XFS doesn't have any properties that i can see as particularly
relevant for audio work, though i don't know enough about it. the
primary things we want are:
* extremely rapid inode and block allocation
* "appropriate" block distribution across the media
Juhana has mentioned an interesting paper from 20 years ago that
suggests that in fact, random block distribution is the best solution
for audio. The whole log-structured thing with XFS sounds pretty cool,
but I don't see it helps audio with its real-time i/o requirements.
Does anyone else ?
