The allocator usually doesn't increment bucket gens right away on buckets that it's about to hand out (for reasons that need to be documented), instead deferring that to whatever extent update first references that bucket. But stripe pointers reference buckets without changing bucket sector counts, meaning we could end up with a pointer in a stripe with a gen newer than the bucket it points to. Fix this by adding a transactional trigger for KEY_TYPE_stripe that just writes out the keys in the alloc btree for the buckets it points to. Also - consolidate the code that checks pointer validity.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
