Andrew,

Configuring filesystem capabilities is still tagged experimental, and
the effect of the "security fix" part of this change is conditional on
filesystem capabilities being configured. This late in the rc cycle, I'm
not convinced that the risk of this bugfix isn't greater than the benefit.

If you disagree, there is another "security" problem with filesystem
capabilities and strace, and I've been exploring the fix. This is also
the last fix I think we need before we can remove the experimental
attribute on filesystem capabilities.

As such, I'll follow this up with four patches. The first two are
bugfixes (affecting kernels configured with filesystem support); the
third is the refactoring; and the fourth removes the experimental tag on
filesystem capability support.

Cheers

Andrew
