Patch series "XArray", v9. (First part thereof). This patchset is, I believe, appropriate for merging for 4.17. It contains the XArray implementation, to eventually replace the radix tree, and converts the page cache to use it. This conversion keeps the radix tree and XArray data structures in sync at all times. That allows us to convert the page cache one function at a time and should allow for easier bisection. Other than renaming some elements of the structures, the data structures are fundamentally unchanged; a radix tree walk and an XArray walk will touch the same number of cachelines. I have changes planned to the XArray data structure, but those will happen in future patches. Improvements the XArray has over the radix tree: - The radix tree provides operations like other trees do; 'insert' and 'delete'. But what most users really want is an automatically resizing array, and so it makes more sense to give users an API that is like an array -- 'load' and 'store'. We still have an 'insert' operation for users that really want that semantic. - The XArray considers locking as part of its API. This simplifies a lot of users who formerly had to manage their own locking just for the radix tree. It also improves code generation as we can now tell RCU that we're holding a lock and it doesn't need to generate as much fencing code. The other advantage is that tree nodes can be moved (not yet implemented). - GFP flags are now parameters to calls which may need to allocate memory. The radix tree forced users to decide what the allocation flags would be at creation time. It's much clearer to specify them at allocation time. - Memory is not preloaded; we don't tie up dozens of pages on the off chance that the slab allocator fails. Instead, we drop the lock, allocate a new node and retry the operation. We have to convert all the radix tree, IDA and IDR preload users before we can realise this benefit, but I have not yet found a user which cannot be converted. - The XArray provides a cmpxchg operation. The radix tree forces users to roll their own (and at least four have). - Iterators take a 'max' parameter. That simplifies many users and will reduce the amount of iteration done. - Iteration can proceed backwards. We only have one user for this, but since it's called as part of the pagefault readahead algorithm, that seemed worth mentioning. - RCU-protected pointers are not exposed as part of the API. There are some fun bugs where the page cache forgets to use rcu_dereference() in the current codebase. - Value entries gain an extra bit compared to radix tree exceptional entries. That gives us the extra bit we need to put huge page swap entries in the page cache. - Some iterators now take a 'filter' argument instead of having separate iterators for tagged/untagged iterations. The page cache is improved by this: - Shorter, easier to read code - More efficient iterations - Reduction in size of struct address_space - Fewer walks from the top of the data structure; the XArray API encourages staying at the leaf node and conducting operations there. This patch (of 8): None of these bits may be used for slab allocations, so we can use them as radix tree flags as long as we mask them off before passing them to the slab allocator. Move the IDR flag from the high bits to the GFP_ZONEMASK bits.

If this option is not set, by default, ktest.pl will look for config-bisect.pl in the following locations: `pwd`/config-bisect.pl # where ktest.pl was called from `dirname /path/to/ktest.pl`/config-bisect.pl # where ktest.pl exists ${BUILD_DIR}/tools/testing/ktest/config-bisect.pl # where config-bisect.pl exists in the source tree.

由 Steven Rostedt (Red Hat) 提交于
Started working on a stand alone program that can do a config bisect. It is based on the config bisect code of ktest.pl. Instead of needing all the infrastructure of ktest.pl, all that is required for config-bisect.pl is two config files. One that works, and one that does not. The goal is to pass in the two files, and it will create a new "good" and a new "bad" config file based on input from the user. After several iterations (calls to this program), it will eventually end with a minimum config value that allows one config to work and the other config to break. The program uses a technique that takes the good config and then makes half of the configs that differ from the bad config just like the bad config. The code will use make oldconfig to make sure the configs that are set are not all converted back due to incorrect dependencies on other configs set in the bad config but not in the new test config. This is still a work in progress, but as it was written while I was working at Red Hat, I want this code to be submitted as such. Signed-off-by: NSteven Rostedt (Red Hat) <rostedt@goodmis.org>
