> - apart from feedback given by @mruffell, to also check if any of librcu consumers are depending on a full membarrier - driven by kernel - for ** shared pages among different processes **
this is a good point, although I don't think liburcu makes guarantees like that, for memory barriers outside of the current process; for example, the -qsbr, -md, and -signal flavors don't use sys_membarrier at all. @mruffell have you looked into that aspect of the change? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876230 Title: liburcu: Enable MEMBARRIER_CMD_PRIVATE_EXPEDITED to address performance problems with MEMBARRIER_CMD_SHARED To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/liburcu/+bug/1876230/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
