commit 0a835c4f090af2c76fc2932c539c3b32fd21fbbb Author: Matthew Wilcox <[email protected]> Date: Tue Dec 20 10:27:56 2016 -0500 Reimplement IDR and IDA using the radix tree The IDR is very similar to the radix tree. It has some functionality that the radix tree did not have (alloc next free, cyclic allocation, a callback-based for_each, destroy tree), which is readily implementable on top of the radix tree. A few small changes were needed in order to use a tag to represent nodes with free space below them. More extensive changes were needed to support storing NULL as a valid entry in an IDR. Plain radix trees still interpret NULL as a not-present entry. The IDA is reimplemented as a client of the newly enhanced radix tree. As in the current implementation, it uses a bitmap at the last level of the tree. It seems that crash didn't adjust to this change and this is causing this following error. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765660 Title: Ubuntu 18.04 [ briggs ]: "ipcs" command fails with error "invalid structure member offset" in crash prompt.
