[RFC PATCH 0/2] xfs: deprecate barrier/nobarrier

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi folks,

In response to the recent conversation here:

https://www.spinics.net/lists/linux-xfs/msg02501.html

I've come to the conclusion that barrier/nobarrier mount options no
longer make sense to maintain. There is no performance penalty for
the vast majority of users to enabling barriersand it's been the
default behaviour for a long time. And given the misunderstanding
that users have over what barriers are and when it is safe to turn
them off, it seems to me like the best solution is to simply
remove the option altogther.

Comments, thoughts, flames all welcome.

-Dave.
