The cxlflash_disk_attach() routine currently uses a cascading error gate strategy for its error cleanup path. While this strategy is commonly used to handle cleanup scenarios, it is too restrictive when function callouts need to be restructured. Problems range from inserting error path bugs in previously 'good' code to the cleanup path imposing design changes to how the normal path is structured. A less restrictive approach is needed to support ordering changes that come about when operating in different environments. To overcome this restriction, the error cleanup path is modified to have a single entrypoint and use conditional logic to cleanup where necessary. Entities that require multiple cleanup steps must be carefully vetted to ensure their APIs support state. In cases where they do not (none as of this commit) additional local variables can be used to maintain state on their behalf. Signed-off-by: Matthew R.
